how do i figure out 30-2x10+5

[jade grotto]

This is multiplication?

[hoary jetty]

Ig

[regal sentinel]

idk

i just wanna know how to do it

[sullen lotus]

Bimdas

[regal sentinel]

what

[jade grotto]

Do you know how to multiply two numbers?

[regal sentinel]

yes

[sullen lotus]

Order of operations

[jade grotto]

Then use the order of operations

[hoary jetty]

2×2

[jade grotto]

multiplications before additions

[regal sentinel]

what is that

[jade grotto]

B O D M A S

On wikipedia check it out

[regal sentinel]

bro ehat

bodmas

bimdas

what is it

[jade grotto]

.

[regal sentinel]

just explain concise to me

im dyselxic

[hazy pilot]

OP how old are you?

[sullen lotus]

Brackets-exponents-multiplication or division-addition or subtraction

[regal sentinel]

16

[sullen lotus]

Thats the calculations you prioritise

[hazy pilot]

alright

[regal sentinel]

my dudes i just wanna know how to do it

[regal sentinel]

ok

[hazy pilot]

just wanted to check you weren't under 13

[regal sentinel]

ok

[hazy pilot]

But yeah this is the order of operations you do it in

@regal sentinel

[regal sentinel]

why

[sullen lotus]

Convention

[hazy pilot]

good question, answer is just convention really

[sullen lotus]

You barely have to think about the order later because it becomes clear with the notation you would use

[regal sentinel]

what about the other order of operations

[sullen lotus]

What other order

[regal sentinel]

idk

u tell me

[hushed badger]

they say they are dyslexic

[hazy pilot]

BIDMAS?

[hazy pilot]

ik, I was just asking since some trolls or actual people below 13 post something like this

[hushed badger]

he's been here for days i think

asking people to teach him basic operations

[regal sentinel]

very motivating guys ty

[hushed badger]

in the discussion channel 💀

[regal sentinel]

my last post took 4 days to get answred

answered

in the discussion channel

4 seconds

how do i do dis

[sullen lotus]

Yeah so always whats in brackets first, then exponents, then multiplication OR division (whichever comes first) then addition or subtraction (doesnt matter how you do them)

[regal sentinel]

ok ty

[hushed badger]

he'll have to imagine the brackets, the questions don't have those

[regal sentinel]

so the root thing

[hushed badger]

like in 6.1

[sullen lotus]

Roots count as exponents

[regal sentinel]

root is like sqaured right

[hushed badger]

no it's the opposite of squared

[regal sentinel]

so 4-6? in 6.2?

[regal sentinel]

oh

[sullen lotus]

Its what number do you need to square to get the number in question

[hushed badger]

2 squared is 4. root of 4 is 2

[regal sentinel]

yeah so 6.2 would be 4 and 6?

no?

[sullen lotus]

No you multiply by 2 three times

Oh 6.2

[regal sentinel]

it says root of 16

[sullen lotus]

Sorry

Yeah root 16 is 4

Root 9 isnt 6 though

[regal sentinel]

3

I mean

so it would be

4-3?

= 1?

is that the answer to the question

[sullen lotus]

Yes

[regal sentinel]

6.3 two negatives make a posistive so it would be just 10?

[sullen lotus]

If you are left with 1 number its the answer

[regal sentinel]

how do u do 6.4 i forgot

its just timed by itself

3 with a small two

would it be 3x2 or 3x3

[sullen lotus]

the number in the exponent is the number of times you multiply it by itself

[regal sentinel]

so 3x3

= 9

[sullen lotus]

Yes

[regal sentinel]

2x4?

so 8

9x8

72

[sullen lotus]

Yeah

[regal sentinel]

?

[regal sentinel]

how do i do 7.1

is it just

6x7?

so i would write 7=

[sullen lotus]

You divide both sides by 6

[regal sentinel]

why

[sullen lotus]

Because the left side becomes x

So the right side would give you the answer

[regal sentinel]

its 6?

ok

[sullen lotus]

No

[regal sentinel]

i get it

wait wdym both sides

i just divide six by 42?

[sullen lotus]

No 42 by 6

[regal sentinel]

oh ye

[sullen lotus]

Because both sides are equal

[regal sentinel]

wdym

[sullen lotus]

They both represent the same number

[regal sentinel]

what does

[sullen lotus]

Because they are equal

The left and right sides of the equal sign

[regal sentinel]

i dont get what u mean

oh

oh yeah

i still dont get what u mean the question is 6x = 42 x?

the formula ur saying is 42/6

[sullen lotus]

Yeah

[regal sentinel]

so 7

[sullen lotus]

Yes

[regal sentinel]

thats what i said??

[sullen lotus]

Oh yeah

I didnt see that

Sorry

[regal sentinel]

so 7.2 3x+7 = 5x -1 x?

is this order of operations too

[timber bobcat]

not rlly

[regal sentinel]

how do i do it

[timber bobcat]

its an equation

the point is to find x so you need to find that x equals something

[regal sentinel]

5x?

[timber bobcat]

3x+7 = 5x-1 right

[regal sentinel]

yes

x?

[timber bobcat]

yeah find x

[regal sentinel]

how

[timber bobcat]

$5x-1 = 3x+7$

[midnight talon]

Bam

[timber bobcat]

what do u think we should do next

[regal sentinel]

5x - 1?

does 5x mean its like in the 50s range

[timber bobcat]

5x-1 cant be calculated since we dont know x

[regal sentinel]

or what is the 5 for

[regal sentinel]

yeah

[timber bobcat]

no its 5 times x

[regal sentinel]

oh ok

[timber bobcat]

the same goes for 3x

[regal sentinel]

dont we need to simplify it

or smtg

[timber bobcat]

yes

u can move 3x to the left hand side and 1 to the right hand side

thats one way to simplify it

[regal sentinel]

ur allowed to do that?

[timber bobcat]

yes

[regal sentinel]

so 7-1

6

[timber bobcat]

no it would be

$5x-3x = 7+1$

[midnight talon]

Bam

[regal sentinel]

oh

i thought u meant the other way around

so 8

[timber bobcat]

yup

[sullen lotus]

It still works the other way around

If you get x to the right side and the constants to the left

Its just cleaner on the left because no negative numbers

[regal sentinel]

yeah

[regal sentinel]

what now

is that the answer

8

[timber bobcat]

nah

5x - 3x simplify that too

[regal sentinel]

simplify with what

[timber bobcat]

if you have 5 take alway 3 how many do you have left

[regal sentinel]

but its x

[regal sentinel]

2

[timber bobcat]

yeah so 2x

[regal sentinel]

oh right

oh yeahh

[timber bobcat]

now we have 2x = 8

2 times what equal 8?

[regal sentinel]

yesyes

4

im starting to get it

[timber bobcat]

yeah so x = 4

[regal sentinel]

can we do one more

im starting to get it

[timber bobcat]

yes

[regal sentinel]

4x + 5 = 6x - 3x

4x+5= 9

[timber bobcat]

nah its minus

[regal sentinel]

oh

[timber bobcat]

not plus

[regal sentinel]

4x+5

not minus

[timber bobcat]

i mean the right side

[regal sentinel]

do u always start on the right side

[timber bobcat]

not rlly

you want to simplify it because you cant simplify 4x + 5

[regal sentinel]

ok so

6x-3x

[timber bobcat]

yeah

[regal sentinel]

3

[timber bobcat]

like before

[regal sentinel]

so 3

[timber bobcat]

3x*

[regal sentinel]

yes

3x

is it 3x3

then

so 9

[timber bobcat]

nah

x here is the mysterious number

not the multiplication

[regal sentinel]

its 3x

ok so

4x +5 = 3x

[timber bobcat]

yup

[regal sentinel]

would we do 4x+5 now

or change numbers

[timber bobcat]

u will need to get all the x on one side and all the constants on one side

[regal sentinel]

so just move

4x over

?

[timber bobcat]

yeah what do we have now

[regal sentinel]

+5 = 3x 4x?

[timber bobcat]

or u can just do $4x+5-4x = 3x-4x$

[midnight talon]

Bam

[hushed badger]

Are my eyes tripping or is that just basic algebra?

[versed pollen]

Pointless chat

[regal sentinel]

idk im bad at it

[timber bobcat]

he doesnt know how to do that alg

somehow😔

[versed pollen]

somehow

[hushed badger]

@regal sentinel it's ok bro we all start at some point it's more to appreciate coz some don't even ask coz they are embarrassed

[timber bobcat]

yeah bro ur doing good

[regal sentinel]

ty bros

[timber bobcat]

curious but you said you were 16 right

how are you starting basic algebra just now

[regal sentinel]

idk i forgot it

i would like to learn

[hushed badger]

@regal sentinel I don't know about anyone but most of the members here ain't a teacher

I'll suggest you to open youtube and search some Indian teacher coz if you are forgetting you don't have your doubts cleared back then

Coz we know the things but ain't no good in conveying those things that's a teacher job

So go do what I suggested

[regal sentinel]

im not forgetting

I just never really tried or paid attention

i have a good memory its not that

[timber bobcat]

i think he just wants quick and authenticated answers

[regal sentinel]

on how to do it

[hushed badger]

Basically you didn't do it in the first place

[regal sentinel]

never learnt

[hushed badger]

Well that's not the way to do maths if he is approaching it like this

[hushed badger]

Yeah so u need a teacher

[regal sentinel]

i just wanna know how to do the problems

so i can solve it on my own

[timber bobcat]

maybe u can watch the steps to do it then practice on ur own

or have someone tell you

[regal sentinel]

yes i just wanted u to tell me the steps

[hushed badger]

Well that's what you need a teacher for broo

We ain't good teachers

If we make you learn how to solve these we will be teaching you basically

[regal sentinel]

just tell me bro

thats all

[hushed badger]

Chat gpt them it will tell them more authenticated way

[timber bobcat]

idk mathcord doesnt like helpers posting full solution

[regal sentinel]

chatgpt is so shit at math bro

[hushed badger]

Says the one who can't even do basic algebra

jk

[regal sentinel]

chatgpt cant either

[timber bobcat]

chatgpt fails at higher level maths

i think

[regal sentinel]

can u guys help me or not

[hushed badger]

Uhh it does sometimes with minor mistakes but it can be real help when you need an approach and cross question it for why this approach it can be real life saver in that

[timber bobcat]

so basically to solve an equation you need to try your best to put all the number with x on one side and all the normal numbers on another side

[regal sentinel]

ok ty

just put the two on each side

and solve it

[timber bobcat]

id rather ask it to show me how to approach it and thought process lol

[regal sentinel]

yeah

doesnt do that

[timber bobcat]

before then it wasnt smart it keeps giving out dumb answers most of the time but the way it thinks is correct

[hushed badger]

That can be good too

[regal sentinel]

ru hindi

[timber bobcat]

It just make assumptions mid way and fail to answer correctly

[hushed badger]

Hindi is a language if you wanna ask my religion I am hindu

[regal sentinel]

yeah same thing

[hushed badger]

Peace out then I am going to get some sleep

[regal sentinel]

Kshatriyas vibes

[hushed badger]

You even know what you are yapping -_-

[regal sentinel]

lol

Dalit?'

[hushed badger]

Man how do you know all these

[hushed badger]

Vaishy

[regal sentinel]

i drink too much lassi

punjabi esque

[hushed badger]

Meri lassi peele

[regal sentinel]

mean while eating pani puri

u guys r too vegan

[hushed badger]

Good finally someone speaking other things than butter chicken and naan

[regal sentinel]

ok bro

can u teach me step by step how to do 4x + 5 = 6x - 3x

and why

[hushed badger]

Actually I have had your vegan food and honestly it tasted like crumbling down piece of paper

We gave flavour too vegetable and all so we don't feel the need to go towards non veg

And no I can't teach you as I am awake for more than 18 hrs and going to sleep finally

[regal sentinel]

indian man teach me

or i will call pakistan

[timber bobcat]

@grok help this man

[hushed badger]

@timber bobcat he the new substitute teacher

[hazy pilot]

for starters, what can you reduce 6x - 3x to?

[hazy pilot]

eh I'd be careful making that joke

[hushed badger]

What can they do 😭😭😭 their general gets medal for losing wars

[regal sentinel]

3?

6x-3x?

= 3x?

[hazy pilot]

it's in the moratorium in #rules to not talk about it

[hazy pilot]

yes 3x

so now we are left with 4x + 5 = 3x

[hushed badger]

@hazy pilot What he said was more violating tbh

[timber bobcat]

you both violates

but i think thats funny ngl

[regal sentinel]

ok

[hazy pilot]

Yeah I know, I was just saying not to because you might get muted by the mods for that

[regal sentinel]

so 4x +5

= 9

[timber bobcat]

maybe ur confused when

we say

3 times x

[hazy pilot]

how did you get 4x + 5 = 9?

[timber bobcat]

its 3 multiply to x

not 3 times of x

[hazy pilot]

or you're thinking x = 3

but it's never stated that x = 3

[regal sentinel]

4x + 5 = 9

4+5

[hazy pilot]

It's not 4x + 5 = 9. It's 4x + 5 = 3x

[regal sentinel]

what

[hazy pilot]

x is an unkown variable here, we don't know what the value is

[regal sentinel]

oh yes

yesyes

[hazy pilot]

How did you reach 4x + 5 = 9?

[regal sentinel]

idk

i just plus 4 and 5

but yes

4x + 5 = 3x

[hazy pilot]

alright so what do we do next

[regal sentinel]

maybe change around numbers

[hazy pilot]

sort of

but notice how you can move the 4x term into the right side?

how would you do that

[regal sentinel]

so +5 = 3x 4x?

[hazy pilot]

close you're missing something there

[regal sentinel]

the plus

??

[hazy pilot]

also you don't need to do +5

[hazy pilot]

no

it would be a minus

3x - 4x = 5

[regal sentinel]

why

[hazy pilot]

Whatever you do in the right said and shift to left side or vice versa, you basically do the opposite operation

[regal sentinel]

oh ok

[hazy pilot]

alright we have 3x - 4x = 5 now

what does 3x - 4x reduce to?

[regal sentinel]

1

1x

[hazy pilot]

close, but it's wrong

[regal sentinel]

what

oh

7x?

[hazy pilot]

no we're not adding

[regal sentinel]

huh

[hazy pilot]

have you been introduced to negative numbers before?

[regal sentinel]

yes

oh

OHH

-7x

[timber bobcat]

maybe this is a youtube video social experiment

[regal sentinel]

no lol

[timber bobcat]

3x - 4x

[regal sentinel]

-7x

[hazy pilot]

no

[regal sentinel]

or wat

-1x

then

[hazy pilot]

yes -x

[timber bobcat]

bingo

[versed pollen]

Yess

[hazy pilot]

so now we are left with -x = 5

just one more thing to do

[regal sentinel]

?

[hazy pilot]

we have -x = 5 right?

how can we turn the x to posistive

[regal sentinel]

yes

two negatives

make posistive

[hazy pilot]

yes

[timber bobcat]

true

[versed pollen]

And..?

[hazy pilot]

and how can we use this fact to make x posistive

[regal sentinel]

we need to get two negative numbers

[timber bobcat]

yes we have -x is our first negative number then what is the second negative number

[regal sentinel]

5 is positive tho

[versed pollen]

So make it negative

[regal sentinel]

ok

-5

[hazy pilot]

yep

x = -5

there we go

[regal sentinel]

oh

[versed pollen]

Yess~~

[regal sentinel]

nice

[hazy pilot]

now if you wanna check if it works, substitute it back to orignal equation

[regal sentinel]

-x = 5?

or 4x + 5 = 6x - 3x

[versed pollen]

2nd

One

The second equation that you mentioned

[regal sentinel]

what about it

[hazy pilot]

trying substituing x = -5

and see what you get

[regal sentinel]

wdym substituing

like switching it out

what part of it

[timber bobcat]

replace every x in the original equation with -5

[regal sentinel]

ok

[timber bobcat]

and calculate it

[hazy pilot]

plug in x = -5 basically

[regal sentinel]

-5 + 5 = -5 - -5

?

[hazy pilot]

that's wrong

it's this
4(-5) + 5 = 6(-5) - 3(-5)

or I guess reduce it to

4(-5) + 5 = 3(-5)

to make it easier to calculate

[regal sentinel]

oh

i thought u meant to supplant every one of them

[regal sentinel]

ur removing all the x's tho

[hazy pilot]

well yeah, that's what we mean by substituting

[regal sentinel]

well i know

-5 is x

but yk

[hazy pilot]

we're replacing all the x with - 5 because x = -5

[regal sentinel]

substitute means like replace

[regal sentinel]

oh yeah

[hazy pilot]

sort of I guess?

[regal sentinel]

why not just replace it totally

[hazy pilot]

wdym

[hazy pilot]

like this?

[regal sentinel]

yeah

whats the point of the other numbers

[hazy pilot]

they are coefficients, they're not meant to replaced

x is a variable remember

for example in 4x, 4 would be the coefficient as it's being times by x

so when we say x = -5 and we plug it in, what we're saying is 4(-5)

[regal sentinel]

oh ok

[regal sentinel]

so we have 4 of -5

[hazy pilot]

essentially yeah

we have 4 lots of -5

[regal sentinel]

4(-5) + 5 = 6(-5) - 3(-5)
but in this +5 = 6 -(-5)

how would u interpret it

[hazy pilot]

how did you get 4(-5) + 5 as being 5?

[regal sentinel]

u said that

[hazy pilot]

huh where

[hazy pilot]

?

[regal sentinel]

if we interpret 4 lots of -5

how would we interpret +5 = 6 -(-5)

[hazy pilot]

By 4 lots of -5, I meant doing -5-5-5-5

[regal sentinel]

thats what i said

[hazy pilot]

you said this though

you forgot the -20 + 5

[regal sentinel]

4(-5) + 5 = 6(-5) - 3(-5)

[hazy pilot]

As I've said before we're not replacing everything with the 5

[regal sentinel]

can u just explain what they actually represent

[hazy pilot]

only the x variable

[regal sentinel]

like why are we putting (-5)

in each

what do they represent

[hazy pilot]

our equation is 4x + 5 + 6x - 3x right?

for simplicity, we just reduce it down to 4x - 5 = 3x

x is an unkown variable here but we solved it and got x = -5

[hazy pilot]

I said that if you wanna check if your x value is correct, you substitute x = -5 into this equation

[regal sentinel]

i understand that

how would that help

[hazy pilot]

because if our x value is right, the LHS (Left hand side of the equation) should equal to the RHS (right hand side of the equation)

[regal sentinel]

oh ok

time to go to a different one

[hazy pilot]

let's work with this equation 4x - 5 = 3x instead of 4x - 5 = 6x - 3x okay?

sure

[regal sentinel]

oh ok

lets do that first

[hazy pilot]

no it's fine, you can to the different one if you want to

[regal sentinel]

4x -5 =3x

ru allowed to just subtract

[hazy pilot]

subtract what?

[regal sentinel]

3

the 3x can u take it and just subtract or can u subtract with any number u please

[hazy pilot]

Okay from here, do you understand everything I said here?

[regal sentinel]

i dont get what u mean by equal

[hazy pilot]

the equal sign here =

[regal sentinel]

like they r equal?

oh

equals to

[hazy pilot]

yeah like 5 = 5

[regal sentinel]

ye

[hazy pilot]

or 4 + 3 = 8 - 1

[regal sentinel]

i get that

[regal sentinel]

7?

[hazy pilot]

they both equal 7 yes

[hazy pilot]

We can move on to the next one then

[timber bobcat]

damn

ur doing good bro

thread passed 500 msg mark

[regal sentinel]

w

[regal sentinel]

its a different type of math question

[hazy pilot]

You can post your question here or make another thread

[regal sentinel]

The sketch shows three lines intersecting each other.
13.1 The size of angle u is °?'
13.2 The size of angle v is °?
13.3 The size of angle w is °?

im guessing i just need to know the formula

[hushed badger]

I would advise learning key concepts about different types of triangles

then learn the angle you make with a straight line

and angles at a midpoint

[hazy pilot]

also the angle theorems too

for v, you can use the vertical angle theorem

[regal sentinel]

yeah so i was right

i need to know the different formulas to solve them

isnt it just multiplying the angles

[hazy pilot]

no

[hushed badger]

Upload the photo to AI and ask it to tell you what key concepts you should learn to solve it. However, make sure the AI doesn't do it for you otherwise you won't be able to learn and it'll do more harm than good.

[regal sentinel]

ok

[hushed badger]

You don't want to just memorize formulas, you want to understand so you can solve harder problems in the future. Besides, understanding will make you memorise anyway. Hence do lots of practise.

[regal sentinel]

The sketch shows a countertop for a kitchen that Anna's family wants to buy. The red line segments show where on the countertop the strips should be placed.

Sketch, viewed from above
14.1 The total length of the strips will be ___ m?
14.2 The area of the countertop will be ___ m²?

what about this one

[hazy pilot]

this one you usually split it into shapes you know

[hushed badger]

Make sure you follow this advise

[regal sentinel]

ok

with this too

[hushed badger]

You just want to know what you need to learn to solve it.

[hazy pilot]

like this

[hushed badger]

YouTube should have all the videos or google it. However, I'm asking you to upload on AI because at-least you're told what to study rather than guessing or getting solutions from others.

Best of luck, we live in interesting times!

[regal sentinel]

The drawings show a red triangle and five blue triangles: A, B, C, D, and E.
Put an X in each row.
16.1 Which of the blue triangles can be moved onto the red triangle using a translation?
16.2 Which of the blue triangles can be moved onto the red triangle using a reflection across a line?
16.3 Which of the blue triangles can be moved onto the red triangle using a rotation around a point
'

what about this

[hushed badger]

Yup

[regal sentinel]

i asked chatgpt before

makes it complicated

[hushed badger]

I'm telling you, it can help you with a lot. However, you want to know what key concepts you should learn and then watch videos on them.

[hazy pilot]

asking chatgpt is not a good idea though

[hushed badger]

Because you're asking it to do it for you.

Rather than telling you what you should learn.

[regal sentinel]

im asking it to explain to me

[hazy pilot]

it often gives false infomation and answers that seems correct but isn't

[hazy pilot]

watch a video instead

the concepts

[regal sentinel]

i have a admission test in one week

hence why i am studying

[hushed badger]

Exactly, that's why you want to be smart with how you spend your time.

If you come on this discord server to ask for help, then you'll have to wait a while just for a solution.

That's risky if you have a week left prior to your exams.

[regal sentinel]

i will give you a example

i am a bit rusty on division so i asked chatgpt

it just make do do complicated division

[hushed badger]

Hence why I'm saying, ask AI what you need to study to solve them. Then it will tell you the topic name, and then you go on youtube to study abit. Then come back to it and try and solve it with your brain.

[regal sentinel]

not telling me what to do

or jumping over steps

[hushed badger]

Don't ask AI to do the maths for you

Ask it to tell you what mathematical concept it thinks you should learn.

From the looks of it, you're asking the AI to solve the question for you. That won't work.

[regal sentinel]

i legit just asked it how to do divison

[hazy pilot]

like long divsion or?

[regal sentinel]

yeah

like on paper

[hazy pilot]

Watching a video is better

[regal sentinel]

i know its like

if we say

43/8

[hushed badger]

Yeah, AI is not smart with math.

Follow my advice

It knows what concepts you need to solve it, but it can't apply it well enough.

[hushed badger]

So, follow this.

[regal sentinel]

8 into 43

so 5 times

[hazy pilot]

43/8 gives you a decimal

[regal sentinel]

40-43

= 3

43 ÷ 8 = 5 remainder 3

?

[hazy pilot]

if you're doing it like that where you're trying to find the remainder, then yeah

[regal sentinel]

well

its 5

the answer is 5

no?

[hazy pilot]

no the answer is not 5

[hazy pilot]

43/8 in decimal form is 5.375

[regal sentinel]

broo

dividing decimals

[hazy pilot]

but that's what it equals to though

[regal sentinel]

ok over again

8 goes into 43

5 times

[hazy pilot]

have you been taught the method for division?

[regal sentinel]

40

main answer so far

• 43 − 40 = 3

43 ÷ 8 = 5 remainder 3

3 ÷ 8 = 0.375

[hazy pilot]

yes the remainder is 3

[regal sentinel]

then u just add the 5

so 5.375

[hazy pilot]

yeah

I mean there's the bus stop method too

[regal sentinel]

idk it

[hazy pilot]

I was talking about this

[regal sentinel]

yeah

thats the one i use

with the line

ok lets do a regular one

so u can see what i do

[hazy pilot]

don't ask me to do long division though

[regal sentinel]

13/82

[hazy pilot]

I'd just use calculator for that one

[regal sentinel]

ok

easier one

maybe like

4/17

4 cant go into 1

[hazy pilot]

I'd also just use calculator for that one

[regal sentinel]

so we say 4 into 17

4 times

[hazy pilot]

lol

[regal sentinel]

oh

ru allowed to do that at test

admission tests

[hazy pilot]

Depends, sometimes yeah. sometimes not

I forgot how to do long divsion, but if they require you to do 4/17 and you can't use calculator

then yeah

[regal sentinel]

u forgot how to do divsion?

[hazy pilot]

no long division

[regal sentinel]

do yk long multiplication

[hazy pilot]

yes I know that way

the column method

[regal sentinel]

yes

sometimes tho

i see people use weird symbols

[hazy pilot]

uh what weird symbols?

could you show an image perhaps

[regal sentinel]

like these

[hazy pilot]

uh

for starters that isn't the column method

[regal sentinel]

i never said it was

i just said sometimes i see people do weird math

with symbols

[hazy pilot]

The symbols have meaning to them yeah, but I'm guessing you're not at that level where you can understand them

[regal sentinel]

can you?

[hazy pilot]

yeah

[regal sentinel]

can u explain what they mean

[hazy pilot]

Well the first one is the gaussian integral

[regal sentinel]

whats that

[long nexus]

hello max

[lament rampart]

hello mixed ballus

[hazy pilot]

I don't really know how to explain it since you don't know the prequisties for calculus

[hazy pilot]

hi

[hazy pilot]

hi x2

[regal sentinel]

whats calculus again

[sullen lotus]

like coordinate geometry of functions using infinitesimal values

[spring oracle]

Hello mxrgd

[hazy pilot]

hello x3

[spring oracle]

Noooooo

[lament rampart]

we are here to end you

nona beat mx up

[spring oracle]

On my way!

[hazy pilot]

It's the study of how things change essentially

[regal sentinel]

can u give me a basic example

[livid jungle]

hi mxrgd

[hazy pilot]

Have you learnt what a gradient of a line is?

[hazy pilot]

hi x4

[regal sentinel]

no

[spring oracle]

Why do only i get a melody

[regal sentinel]

wait

yes i have

[hazy pilot]

Then as i've said before, I can't really explain it to you that's understandable. You'd have to first master the prerequisites

[regal sentinel]

its like x and y

and u find the midpoint

yes?

[regal sentinel]

yes u can

[spring oracle]

This is so sullyable

[hazy pilot]

no?

[regal sentinel]

thats not a word

yes it is

its like this

[spring oracle]

Yea i made it up

[regal sentinel]

i know what it is

so 8

and u move 3 up

x and y axis

[sullen lotus]

the concept could be explained but the actual definitions and calculations are way too difficult for your level

[regal sentinel]

try

[hazy pilot]

I was talking about the general form for it

[regal sentinel]

yes ik

[sullen lotus]

wait the actual slope of a line?

i thought we were talking about calculus lol

[hazy pilot]

yeah lol

[sullen lotus]

but anyway you still need to know how algebra works before you get to functions like this

[hazy pilot]

Just starting from the basics

[regal sentinel]

can u give a example of a basic one

[regal sentinel]

yes ^

[sullen lotus]

the slope of a line is how much the y value goes up per x value

[regal sentinel]

yes

[hazy pilot]

that's a basic one essentially

[regal sentinel]

ok

see ez

[spring oracle]

Have u ever seen a y=mx+b?

[regal sentinel]

isnt that a line across the axis

[hazy pilot]

the gradient m represents how much the the y value goes up per x value

[sullen lotus]

sorta

[spring oracle]

Can u find what m and b are for this graph?

[sullen lotus]

just the equation of a line if you were to graph it

[regal sentinel]

what m and b

i know y and x axis

[sullen lotus]

m is the slope and b is the point on the y axis where the line crosses it

[spring oracle]

@regal sentinel

[hazy pilot]

to clarify it's this $m=\frac{y_2-y_1}{x_2-x_1}$

[regal sentinel]

ohh

[midnight talon]

឵឵MxRgD

[spring oracle]

and u already have a lot of points to choose from in the graph!

[hazy pilot]

[regal sentinel]

i forgot is x or y the lateral line

[hazy pilot]

wdym?

[regal sentinel]

the flat line and the line going up

which is x and y again

[hazy pilot]

the x axis is horizontal, the y axis is vertical

[regal sentinel]

oh yeah

[spring oracle]

It’s written on the graph too

[sullen lotus]

x is the horizontal coordinate of any point of the function, y is the vertical coordinate corresponding to the point

[spring oracle]

@regal sentinel ok after reading this can u tell me what b is here

[regal sentinel]

m would be 3 and b would be 2

[spring oracle]

Ok so where does the line cross the y axis?

In what point

[sullen lotus]

m is the amount y changes per x coordinate

it goes up 3 over the course of 6 x coordinates

[lament rampart]

mxrgd teach me d/dx pls

[sullen lotus]

!occupied

[hazy pilot]

bruh

[lament rampart]

[lament rampart]

😢

[sullen lotus]

what has this forum turned into lol

[regal sentinel]

the y is the flat one

just to calrify

[hazy pilot]

the y is the vertical

[spring oracle]

No its the other on

[regal sentinel]

oh ok

[hazy pilot]

flat one (horizontal) is x axis

[regal sentinel]

so the vertical one goes up 3 and the flat one 8 so 11 total

[hazy pilot]

how did you get the horizontal across as 8?

it says 6

[regal sentinel]

well the lines meet at 8,3

it first meets the flat line at two

0,2

[hazy pilot]

ah okay you meant the point

[spring oracle]

The blue and orange lines aren’t part of the graph its just demonstrating where the point lies

[regal sentinel]

then what r we talking about

[spring oracle]

Ok so what is b ?

[hazy pilot]

you don't really need to find b, you can use this form instead
y-y1 = m(x-x1)

[spring oracle]

Where does the line cross the axis circled in green

[regal sentinel]

oh at 0,2

[spring oracle]

Yea but its right there

[regal sentinel]

or 0,3

[regal sentinel]

what line

[hazy pilot]

fair

[regal sentinel]

at 2

[hazy pilot]

do you know what the b is?

it means y intercept

[spring oracle]

The once circled in green the vertical one the y axis

[hazy pilot]

this is when the it crosses the x axis, meaning x = 0

[regal sentinel]

i dont understand ur question

[regal sentinel]

what about it

[spring oracle]

Where does the line cross it?

Ok hold on just a sec

[regal sentinel]

-1?

[hazy pilot]

yes that would be b

[spring oracle]

Where does the green line and the red line meet

[regal sentinel]

yes i said

[spring oracle]

YES!!

[regal sentinel]

^

[spring oracle]

That is b!

[regal sentinel]

oh

i get it now

[hazy pilot]

alright so we're left with y = mx - 1

[regal sentinel]

lol

[hazy pilot]

now we just need to find m

[regal sentinel]

what is m again

[hazy pilot]

m is the gradient

[regal sentinel]

oh

so changes

[hazy pilot]

.

this here

[regal sentinel]

idk what im looking at

[hazy pilot]

but remember that it goes 6 across and 3 up right?

how can we use that to find the gradient

[regal sentinel]

it went 8 across?

[hazy pilot]

it did not go 8 across

[regal sentinel]

8,3

[hazy pilot]

(8,3) is a point yes

[regal sentinel]

what ru asking me

[hazy pilot]

but i'm asking how much it goes from (2,0) to (8,3)

[regal sentinel]

oh

[hazy pilot]

there are blue and orange lines for a reason

[regal sentinel]

6,3

[hazy pilot]

okay and how can we use this fact to find the gradient m?

[spring oracle]

So it goes 6 horizontally (flat) and 3 vertically (up)

[regal sentinel]

yes?

is this correct

[spring oracle]

Yes

[regal sentinel]

ok

what now

[spring oracle]

@regal sentinel

[regal sentinel]

idk

isnt that the answer

[hazy pilot]

no

okay you can think about it like this. $y_2-y_1 = 3$ and $x_2 - x_1$ = 6

[hazy pilot]

use this formula here

[spring oracle]

$m=\frac{y_2-y_1}{x_2-x_1}$

[midnight talon]

nona_<3

[regal sentinel]

i said 6.3

??

[midnight talon]

឵឵MxRgD

[hazy pilot]

yeah you did but you haven't found the gradient m yet

[regal sentinel]

how do i do that

[hazy pilot]

@regal sentinel this

[regal sentinel]

ok

what do we do with this

[spring oracle]

So pretty did u write this yourself?

[regal sentinel]

very relevant

[sullen lotus]

wait fixed it rq

[regal sentinel]

what do i do to find it

[hazy pilot]

as i've said before here

[regal sentinel]

bro

[hazy pilot]

use those to substitute into the formula

[regal sentinel]

ok

y2 - y1 = i2 - i1 = 6

[hazy pilot]

Or I guess you can think of m = rise/run

[regal sentinel]

what is i2 and i1

[sullen lotus]

third and last time ill send it lol sry

[unique glacier]

What did u use to make the chart it looks clean @sullen lotus

[spring oracle]

Where did u get the i from

[sullen lotus]

canva

[regal sentinel]

i dont know what im trying to look for

[unique glacier]

Canva is so beautiful

[regal sentinel]

he said that

[regal sentinel]

or u did

can u just tell me what i need to look for

idk what im looking for

[unique glacier]

R u looking for M? @regal sentinel

[spring oracle]

We are building an expression that represents the graph u sent earlier

[regal sentinel]

ok

[hazy pilot]

yes that's what we are doing

[regal sentinel]

cool

[unique glacier]

Oh word

[regal sentinel]

but what am i looking for

like what am i supposed to look at

[hazy pilot]

the gradient m

[unique glacier]

U looking for M

[regal sentinel]

what is tha

WHAT IS M BRO

[unique glacier]

Da slope

M is the slope

[hazy pilot]

m is the gradient

[regal sentinel]

m 1

[unique glacier]

Or thhat

[regal sentinel]

0,b

ok so, m 1,1?

[spring oracle]

We already found that to be -1

[regal sentinel]

ok

[spring oracle]

M is not a point

[hazy pilot]

ImOkaeley said what m is from here @regal sentinel

[regal sentinel]

then what am i looking for

oh y

[hazy pilot]

as we've said, we're looking for m here

[regal sentinel]

y is the vertical one

[spring oracle]

Yes the green one

[sullen lotus]

you find m the same way you would find speed using distance and time

[regal sentinel]

its 4?

2-4?

[hazy pilot]

no

okay if it makes simpler, we can think of gradient m as to rise/run

[hazy pilot]

from here look

[hazy pilot]

look at here, what would our rise and run be?

[regal sentinel]

1?

[hazy pilot]

no that's wrong

rise = how much is going up (the y vertical). run = how much is going across (the x horizontal)

[regal sentinel]

like how many times?

[hazy pilot]

you can think of it how many times we go up and across each square, yes

[regal sentinel]

but there are no numbers

[hazy pilot]

I meant this one here

[sullen lotus]

its about the formula

understanding it

[regal sentinel]

oh ok

[regal sentinel]

ok so to clarify

its going up to 4?

but they meet at 2 or 8 depending how u look at it

[hazy pilot]

no it's not going up by 4

[sullen lotus]

can i ask what the objective is rn

[regal sentinel]

idk what u r asking me to find still

[hazy pilot]

to find m still

[sullen lotus]

oh my god lol

[regal sentinel]

what is m

idk what am i looking for

[hazy pilot]

I'm trying to simplify it as best as I can 😭

[sullen lotus]

ok see the point (2,0)

[regal sentinel]

like where they meet

yes

2,0

i said that

where they meet

[sullen lotus]

how much does the line go up when you go across one x coordinate

[regal sentinel]

4 is the limit?

so 4

[hazy pilot]

no it's not 4

[sullen lotus]

whats limit

[regal sentinel]

ok just show me

[hazy pilot]

look at the number next to the blue line

[regal sentinel]

the highest number is 4

[sullen lotus]

iron

[regal sentinel]

0

or 3

[sullen lotus]

whats the y coordinate where x is 2

[hazy pilot]

it is 3 up but i'm not sure how you got 0

[regal sentinel]

depending which line

[regal sentinel]

bro

i said 3

[regal sentinel]

3-

[sullen lotus]

its not

what is y where x is 2 in this specific line

[regal sentinel]

u said it was

0

[sullen lotus]

yes

[regal sentinel]

i said 0

[sullen lotus]

now when you go to where x=3

now what is y

[regal sentinel]

ur confusing me bro idk

[sullen lotus]

what is the y value where x is 3

[regal sentinel]

0

[sullen lotus]

thats where x is 2

[hazy pilot]

we're talking about x = 3 now

basically what is y here from (3,y)

[regal sentinel]

oh

other 3

[hazy pilot]

yep the other point

[regal sentinel]

3

??

[sullen lotus]

how high is the point on the line at x=3

[hazy pilot]

it's not 3

[regal sentinel]

wtf is x = 3

[hazy pilot]

the point at which x = 3

how high up is it?

[regal sentinel]

its flat

wdym how high up is it

and the other one

its 3 or 4 up

depending if u count the round thing

[regal sentinel]

bro

0.5 cm

0.5

one half

[sullen lotus]

yes

[hazy pilot]

I think it's better to do x = 8 instead

[regal sentinel]

so its one half

[sullen lotus]

so at x=2 the y value is 0

at x=3 the y value is a half

how much did y change

[regal sentinel]

what

[hazy pilot]

nvm I see where you were going with this

[regal sentinel]

ok x 2

y is zero

cause its flat

its like one half with the line

the line changed one half

[hazy pilot]

yeah it changed one half

and that one half is our gradient

[regal sentinel]

ok

ok

so the answer is one half
