Which "number multiplied"?

raw wigeon Jan 14, 2025, 2:22 AM

Like

X 2 and X 3

wooden pulsar Which "number multiplied"?

I don’t get why they are smaller

wooden pulsar Jan 14, 2025, 2:23 AM

#

raw wigeon I don’t get why they are smaller

...because what's the goal?

raw wigeon Jan 14, 2025, 2:23 AM

#

To find x and y?

wooden pulsar Jan 14, 2025, 2:24 AM

raw wigeon To find x and y?

How?

raw wigeon Jan 14, 2025, 2:24 AM

With um

#

linear combinations

opal cloak Jan 14, 2025, 2:26 AM

#

raw wigeon

to be blunt, the standard method is to identify a variable being cancelled then create a linear combination of the system s.t. the variable can be cancelled

#

in simpler terms, they find the LCM of the coefficients of the variable wanting to be cancelled

raw wigeon Jan 14, 2025, 2:26 AM

#

Ohhhh

#

But how would u know that is the lCM

opal cloak Jan 14, 2025, 2:27 AM

#

you jsut cslculate it

raw wigeon Jan 14, 2025, 2:27 AM

#

I forgot how but ok

opal cloak Jan 14, 2025, 2:27 AM

#

lcm(3,4)=12

raw wigeon Jan 14, 2025, 2:27 AM

#

I learned that so long ago I forgot

#

like. 3 years ago

opal cloak Jan 14, 2025, 2:28 AM

#

so you would multiply the bottom equation by 4 and the top one by 3

raw wigeon Jan 14, 2025, 2:28 AM

#

Ah

opal cloak Jan 14, 2025, 2:28 AM

#

raw wigeon I learned that so long ago I forgot

find a multiple of one of the numbers s.t. it is a multiple of the other

raw wigeon Jan 14, 2025, 2:28 AM

#

I guess

#

oh is this right can u check my work

#

#

Like the right one

raw wigeon I forgot how but ok

In general, first you calculate gcd(a, b) with the Euclidean algorithm, then lcm(a, b) = a * b / gcd(a, b).

raw wigeon Jan 14, 2025, 2:30 AM

wooden pulsar In general, first you calculate `gcd(a, b)` with the Euclidean algorithm, then `...

Oh yeah the little trees

#

or whatever

wooden pulsar Jan 14, 2025, 2:30 AM

#

Though with these small numbers you can just eyeball it.

opal cloak Jan 14, 2025, 2:30 AM

#

raw wigeon

yeah that look good

raw wigeon Jan 14, 2025, 2:30 AM

#

opal cloak yeah that look good

ok ty

opal cloak Jan 14, 2025, 2:30 AM

#

usually (not recommended!!!) you can just mutiply the 2 numbers together if they’re small enough and both prime

raw wigeon Jan 14, 2025, 2:31 AM

#

How would you know what numbers are prime

wooden pulsar Jan 14, 2025, 2:31 AM

#

opal cloak usually (not recommended!!!) you can just mutiply the 2 numbers together if they...

...I mean, if the numbers are both prime, then they're coprime and their LCM is their product.

wooden pulsar Jan 14, 2025, 2:31 AM

#

raw wigeon How would you know what numbers are prime

...do you know... what a prime number is?

raw wigeon Jan 14, 2025, 2:32 AM

#

well yeah….

wooden pulsar Jan 14, 2025, 2:32 AM

#

raw wigeon well yeah….

Then you can just... check.

raw wigeon Jan 14, 2025, 2:32 AM

#

I use to have one of those lists

#

my teacher gave me

#

and she like gave us all prime numbers

wooden pulsar Jan 14, 2025, 2:32 AM

#

Okay, no.

raw wigeon Jan 14, 2025, 2:32 AM

#

to use on the test

wooden pulsar Jan 14, 2025, 2:32 AM

#

She didn't.

#

She literally can't have.

#

There's infinitely many.

raw wigeon Jan 14, 2025, 2:32 AM

#

well I think she gave up to 100

What is a prime number?

opal cloak Jan 14, 2025, 2:33 AM

#

FLOOSHED

raw wigeon Jan 14, 2025, 2:33 AM

#

I forgot…

#

despair

opal cloak Jan 14, 2025, 2:33 AM

#

it’s a number that can only be divisible by itself and one

wooden pulsar Jan 14, 2025, 2:33 AM

#

...a prime number is a number with exactly two factors; one and itself.

raw wigeon Jan 14, 2025, 2:33 AM

#

OHHHH

opal cloak Jan 14, 2025, 2:33 AM

#

in other words gcf(p,n)=1 where n is a number and p is prime

#

unless n=p then gcf is p

wooden pulsar Jan 14, 2025, 2:33 AM

#

opal cloak in other words gcf(p,n)=1 where n is a number and p is prime

(and n =/= p)

smart people

this is basic nt

but also kinda intuition based
