bro i spent 25 minutes on one freaking questin
just discuss tomorrow
That’s like
and then I didn't get pass questio n13 bro
Contest math prep right there
Did you take 12 or 10
I’ve spent like
10
Oh
ik chat dont judge
5 hours on amc problems before
lol
its kind of funny how much my aime practice scores range
bro cuz i don't know the shortcuts n stuff so i literally solve everything
one test i get a 5 and the other i got a 13
where r practice tests
Just
just go to previous tests
oh alr
Can make custom mocks
i had a lot of math kids in my old middle school
but like
maybe bc we're the top school in the state 😛
they werent that good
alr bro
we were at least last yer
wait
and aime
is amc8 18 good in 6th
a kid at my school got 7th grade jmo hm
yeah
do you want the good or bad answer
same
idc its my brothr
wait not my school on my team
so bad answer
yeah 18 on amc8 is 💩
bro hes such a big back cuz he sits on his computer all day
alr
damn
wait i should tell him that tho
bubo what did you get jmo index
yes
last year
repeat word for word
lowkey if I understand math its fun
bro is spitting straight facts
what about the year before
is that good
9 now
its amc 10 + 12 right?
yes that is amazing
ok im gonna kms
no thats amc10+aime
AHIFAHOIFS
i strive to be like you
im in 8th grade and trying to get jmo rn
that is actually crazy
i feel so dumb rn bruh
some guy
Wait any recommendations
is there a page with just all the info I need for the amc 10?
No
Its
Broad but concise
Both
o
i really dont want to read evan chen's olympiad book
this was the persona i was talking abt lol
geo
idk if i can trust u...
trust me aops forums
forums 💀
alr im gonna sleep and check it now tomorrow cya
They have everything
A smart mathametician is the one who sleeps the most -Tsun zu maybe
tsun zu a hack
fr
Goodnight chat
wtf
what
on b
o nice
i learnt it from looking at a shrek pic
i did not cook
I got a 72
2 options Basis, or some other
Wait we can talk about the test now right?
Since 4 min ago
back to the grind
i’ll figure my score out later today prob
i’d be surprised if i did well tho
I swear I’m tweaking
was bored and just guessed D for a bunch
rip
I spent 25 minutes bashing the modular arithmetic one because I somehow got 19*2 = 34
And it was literally so easy
which one
7^2024 one
the 7^2024 one
I swear so easy
i just checked first 4 mods
and hoped it was a pattern
Which one?
and there was
Bro the 7^2024 one
7^2024 + 7^2025 + 7^2026 mod 19
I just did 72024 +77^2024 + 49*7^2024
that’s so smart oml
You could add (1+7+49)7^2024 =57(7^2024)=3*19(7^2024)=0(mod19)
😭😭😭
i had 0
let’s go
well i realize that not
so 0 remainder
does anyone know why this is wrong on this parallelogram one i cannot see my problem
what was the sol for that parallelogram one
I skipped the parallelogram one
Yeah I saw that but I somehow mapped 19*2 to 34
i had this
whenever it sends
i got 9/4
😐
which was NOT. an answer
bru the photo won’t send
Oh I didn’t even try that ngl
I think you could’ve cord bashed it
i’m too lazy for that
I didn’t even try it tho I just spent all my time on the modular arithmetic bc I was getting answers that weren’t options
rip
I’m crashing out
I literally just had to add 19 and 19 to get 38 and I would’ve gotten it in like a minute
And I could’ve gotten like 3-4 more questions
😭
Which one was that
The one of buckets
Cool
Idk man these tests felt completely different from the past years
I don’t think they’re out yet
Thebeautyofmath has some
I sillied #4 and it was such a sad mistake
I found n > 63
rip
which one was that
Bins one
oop
A b c d e
i remember
Silliest
i forgot triangle number formula thingy and had to bash it a lil
I sold ngl I just didn’t try
i may have messed it up
i forgot to check my work
welp
yeah i went 1 over oh well
🤷♂️
I guess that’s why I didn’t try
it’s whatever
Questions were hella out of place
i agree
Maybe they shuffled some around
i had online so idk
Same
My computer stopped working halfway tho
I had to use the teachers
Wasted like 5-10
Was this d
Yes
Hey guys. I went to the national math olympiad today and I was stuck on a problem and didn't solve it. Maybe someone can help me answer it.
I am searching for all the number $n=a^3bc$, whith a, b and c being positive integers and $0 \textless a \textless b \textless c \textless 50$ that satify the following equation:
$\frac{1}{a^3} = \frac {1}{b+1} + \frac {1}{c+1}$
Apart from (1,1,1) i could find any other solutions. Btw 1<1<1 is false so it esen even a valid answer
Oogy Boogy
I'm also gonna post it in a help channel
what score do yall think you got on 10b
i spent 25-30 minutes on the $7^{2024} + 7^{2025} + 7^{2026}$ one because i was tweaking and thought 19 + 19 = 34 and 19 * 3 = 54 so 🤷
damn
reaver
i factoried it right
wait what was question 12
idk i took digital so i dont really remember
where 100 students from different coutnries
same ngl
was the answer 100?
Yeah in that case where you are stuck because of silly then skip and move on, maybe come back later
the languages question
Can’t let it drag down other parts of the test
i was confused by the 100 students one
what was the answer to the "100 students each speak different languages" questoin
yeah me too
i just skipped cuz it made no sense to me
Random math has solutions
i thought it was 100
If you search on Google
where send link
The AMC 10 and AMC 12 are a 25-question, 75-minute, multiple choice examination in middle school mathematics designed to develop problem-solving skills.
maybe ill do the rest of the questions later
and try to do as many as i can before looking at solutions
i swear 24 was easy
the one with the P(m)
I got 9 for that one
Because if everyone speaks 4 languages, then 9c4 > 100
i dont even understand the question
It’s basically everyone has to speak a language that someone else doesn’t speak, and since everyone speaks the same number of languages, that can happen if two people don’t speak the exact same languages
It’s kinda hard to understand
P4?
Oh rip
Idk
im gonna go back through all the problems w/o looking at solutions
Answered the first 24
WHATT
But not sure how many I messed up
teach me your ways
Hopfully
what did you get on the a
124.5 😭
Thanks
i took paper first and then digital
what grade u in?
10th
nice
i got digital before paper even though i took B
How about you
You still have more year to take the amc 10
That’s good for 8th grade
i just started comp math so i have a ton of sillies
ig
72 on this one 😦
Are solutions out?
nice
Wow
10
im in Calc AB rn
cool
tryna skip BC and go to multi-linear
Cool
gonna see if i can do math research maybe cuz i like math
i needa do better at comp math cuz im slow
and im gonna grind leetcode too trust
same 😭
How do y’all train for comp math?
i did a CTY class but then it wasn't too helpful so i just stopped 1/4 of the way and studied using online resources
- tons of past
cool
oh bet
Oh ok
this looks cool
cool
Just recreationally
whats ur guys rating
yeah ig or online
Around 1000 on chess, 2000 on mathdash
cool
Hbu
im like 700 uscf 💀
i dont play chess that much
Nice
yeah recently i had a 3 day chess tournament and I am going to invitationals only for my state :)
yes
niceeee
any of u play piano too? just curious
idk
whats his lichess rating
ur brother
or online
rating
(and whats his username im curious lol)
2000 uscf is insan
blitz?
yeah
2163 i think
139.5
teach me your ways 🙏
Practice
Hello Mathematicians all over the round earth,
Myself AK here. I am preparing for the second toughest exam in the world JEE, I have maths going really tough. I love calculus, but allergic to the complex language of LIMITS, Continuity and Differentiability, I am somewhere able to do differentiationa n integration easily, but okok it is. I have my first attempt on 22.01.2025
I also have problems in algebra, geometry, specially trigo, coordinate geometry, conics and other topics. PNC is the most easier, but its quite dicy for me, as my thoughts are always flopping on me.
I need help seriously. Please advice, give me some medicines professors.
For the a or the b?
b
U got ur score back already???
My fide rapid is 1600 and standard is 1300😭😭😭
???
b already finished?
Oh oki
Dang I got a terrible score
I think
😓
Any predictions for cutoff
I made some mistakes on my test😢
I think I still qual for aime but probaly not dhr
😔
Said to be around 96-105
This years was a little hard
Which one
B
any 12b cutoff predictions?
30000
Reliable
I got 87
AIME cutoff for 12b in 2023 is 88.5, in 2022 is 81
Somewhat I will not qualify maybe
寄
bless that cutoff will be lower
I didn’t qualify for aime
If I qualify aime next 3 years will that be good for top coleleges
You still have a lot of time
Really math king
I only get 80ish in amc10 when I'm 9th grade
I mean that you are the really king of math
Potion of bless of god of math
Only people with magic can get that much score
My brain already degenerated
Now I'm dumb on math
Yea I sorta messed up the test
I remembered some questions I had doubts on and got different answers
:/
guys what other math comp can i do as a junior other than amcs
It just depends on where u live
There isn’t really many other national comps
US
U can try searching ur local universities and see if they have math meets
do you have any recommendation
ok
What state r u in?
california
There’s a lot of opirtunities there
Try searching if cal tech or Berkeley have math meets
They are stem schools so chances are they might have them
ok thx
Np
yk they dont look at it unless you show it
you arent negatively impacted if you dont
its just a bonus if you do
I did a bunch of mocks during summer and fall
Also prepared by grinding a website called mathdash
when does 12b answer key come out
Lol
does mathdash have non-amc problems in it
is that the actual answer key or is it made by somebody else
It was sent in a different server
can you send me the server
Is math dash free?
i missed the AMC by oversleeping 💀
Yes it is
You can pay extra to get more features and private coaching, but it’s free to use the website
Yeah
Ok Ty
How long have u been studying comp math
A little over a year
I just started like at the end of summer
I kinda didn’t really prep until like a couple weeks ago tho
How did u get a 130+ 😭
Skill issue
i studied like for a year and was able to get a 124.5 in 2023
does anyone have the 10b answer key
what is ommc not leak right
It’s like a math olympiad server
And no it’s not a leak
This was released this morning
@ornate coyote
bruh
how did i mess up on 19
am i stupid
i sillied 19
meh 139.5 still decent
SAME
it was the fastest way
Casework on the shoes was was so stupid
i skipped 15-18 due to trauma from “how many”
lol
and i forgot to look at 23 24 25
the entier test was basically just elementary math
24 should be like problem 12
What is cutoff prediction
mm
someone in my ms got 120
yeah pretty much
110 not possible tho so its fine
a kid in my math group got 150
Same lol
Yeah that definitely aime qual
i think aime is like top 8% for amc10
what are you getting on amc8
im bouta get a 13
18/25 lmao i cheese
u in 8th grd too?
ye
Fr
i think ill only need 9 on the aime for jmo
how is index calculated
what state u in
washington
😭
i dont think 96 would qualift
?
I skipped the parallelogram and students languages ones
…
cause like
What did u muss
19
and 22
its like all of them can be solved with simple concepts just that it takes a lot of time
Cap
I thought some were hard concepts but takes little time
For me atleast
U could be dif
like which ones
for the remainder of 125 when n^100, I used eulers thorem which is kinda a hard concepts
And the pipe on was weird I knew there was a formula for it but I forgot it
i think that kind of problem appears a lot withoout a lot of variation
huh?
the eulers totient
ive seen a really similar one
well pretty much the last few questions are really easy
for an amc
Also how do you do the parallelogram and 100students w diff languages ones
thats true
so basically you can just assume the parallelogram was a square
from that point its simple
and for the 100 students diff language i just made as many combinations of the x languages there are and assign one to each student
so 9 choose 4 =126
Ohhh
well ig this test more depends on experience and speed because there are a lot of these little tricks in the test'
and a lot of easy questions that take time
Ohhhh
Bro I just realized I misread the problem
I thought it asked how many languages each student spoke
😭
oh damn
i attempted 20 and only got 2 wrong tho so im really happy
a lot of time
and basically starting at a young age
predicting cutoff at like 99 or 100.5
When did u start
did anyone actually get 25 done
I did
I skipped some and did it
it wasn’t that bad it was just sytems of equations
me
i think a lot of people did cause it was just a system of equations
6th grade
orz
um
💀
sus
yeah bc if it applies to parallelogram it must apply to square by defiition since square is parallelogram
it reminds me of that one aime question where you can assume the parallelogram is a line
Isnt rhombus a square ish?
mr president
its a tilted square
I was learning how to add fractions in that grade:)
i was learning how to food at that grade
i love those types of questions
you can sign up at a school or organization, i think
oh
idk my mom just does it
how did you start in 6th grade
What is some problems in math competitions
by being in 6th grade and starting
aops has past AMC and AIME questions
check some of those out
?
wdym
i just signed up for amc8
did practicee
I don’t even know what that is am I just dumb 😢
those are two american math competitions
or did you mean aops?
it’s a website
if you google “2023 AMC 10A questions” it should be among the top search results
.
ah alright thanks
american mathematics competition i think
I saw, thank you:3
o alright
i thought it was intermediate
what’s the e, exam?
hardly matters as almost nobody calls it by its full name
erm
am i wrong
there are more
i never said there weren’t
are you suggesting i send this user to mock the USAMO when they’re asking how to do math competitions?
what did you get on 10b?
no
make them mock amc8
that’s still the AMC
omg its the bay harbour butcher
Jesus Christ Morgan
whats prediction qual aime 10b
I hope its <100
same
what grade are u in
how di find a closed form to hte number of ways to fill a 10x10 grid with an integer from 0-9 such that each row is nonincreasing from left to right and each column is nonincreasing from top to bottom
Senior 💀
If I get a 120 on the amc 10 but have never solved an aime problem in my life, should I attempt to qualify for the jmo
did u take the a?
aops books fun
just prep for aime
doubt you could qual for jmo with 120
most of my math friends got a very high score on this amc
most of my friends who trying to make jmo got 138-144
How do you meet these kids
How hard is it to get 1-8 questions right on the aime
The kids in my school ain't the brightest
they arent in my school i was trying to find a team to do some math competitions with
Makes sene
i am traumatized by amc 10 A
meh
you need to get at least a 10 to make jmo if you got 120
that makes sense
aime questions arent that hard up to 10
at least 12B was ez
they arent THAT hard
@ornate coyote did you take amc
a lot of the time they have easier solutions but you need a lot of training to actually know how to do them
yeah
which ones
10a and 10b
yeah 10a was insane
i got 133.5 and 139.5
what grade r u in
<10
ok...
lwk I screwed it up
fr
Stop cooking 🍳
im not saying they arent hard or difficult to solve in the real test
im just saying
the concepts are not that hard to understand
i mean most of the time
its like
about applying them in weird ways
so basically you need to do every single aime test that has ever existed
That's literally all of competition math bro
None of the concepts are harder than high school
But the applications are absurd
AIME prep is wild: Just do every AIME and lower oly test in the universe and you'll be fine
im gonna end up doing all aimes from 2001 and a bunch of MPFG tests
before the aime
Bro its not that deep
These contests are lowkey fun
true
i just tend to get up and walk around to think
i just hate doing work that i have to do
Lowkey just chill
Not that bad
If you're worried about an AIME score that exceeds like 8, you probably are capable of making JMO/AMO anyways
Evan Chen mentioned that you shouldn't try to perfect AIME
just practice AMO/JMO if you're already getting 10 or more and you'll be making much more use of your learning
i cant consistently get a good score on aime soo like i wanna solidify my brick of knowledge called a brain
My aime scores are all over the place over the last few years, so I can relate
yeah this is true
What grade ru bean
thats good
8
lots of practice tests
idk
just experience with amc10 type problems
ive done lots of mathcounts trainer to speed up and know the concepts
@radiant jasper
Idk ask them
you seem like the type of guy
gotchu
@radiant jasper imagine not aime
shut
uh huh
and got 2 wrong
uh huh
thats like borderline
"you didnt take it
act yes
wha
score reveal
145.5 on a
DAYUM
mid score
ikr
that the hell is a math
Hello, how does this work 😭
you solve problem and win
Ohhh
my teacher is actually pissing me off i have to do geo homework
like basic introductory geo homework
I have to do geo next year and im not excited im alr procrastinating my alg 1 honors AND for geo im gonna have my alg teachers husband 💔
rip
are you like a mopper or smth
NOOO
😔
yeah burn the books or something idk

Im trying to but i forgot to turn in the module for my VR project and thats a test grade so i gotta turn it tomorrow
We got to do VR but the bad kids in our class are getting in taken away
are they out yet?
Lol what a coincidence
I go to that math center
I Didnt think u guys would find the solutions
I pray i gt 102
I’m not American, wt award i can get by participating aime
usajmo usamo if good enough
i also not american
but you get certificate even though you didnt participate
Isn’t that only for American?
Amooebass
wat
and they've further tightened the eligibility
for the American IMO team
previously you could be a resident or a citizen of Canada and you could go on to represent the US
which is a smart move
if someone in Canada is really that good then let them compete for the US
W thinking
There was this dude from Canada who like won three or four gold medals in the imo
It was in the 1990s
Wait you can’t anymore??
nope, according to Wikipedia
why not represent your home country
instead of the US
yeah I never said you couldn't
I learnt too late about CSMC
Missed the sign-up window
I got qualified to AIME in 2021 but since then I never took any MAA Mathematics competitions
These years a bit crazy, online tests
Very challenging
@latent bough I remember a few days ago I told you that the difficulty of CAMA contest was harder than AIME, I have been revising the problems and I can now tell you that the problems from the basic level of our contest are of about the same difficulty of the AIME.
So difficulty should not be an issue.
Great
funny story
do you know arran fernandez?
Arran Fernandez (born June 1995) is a British mathematician who, in June 2013, became Senior Wrangler at Cambridge University, aged 18 years and 0 months. He is thought to be the youngest Senior Wrangler ever.
youngest senior wrangler (topped cambridge exams) aged 18
well he really wanted to do the IMO
but he wasn't good enough for the UK team
so he went on the look
anyway he eventually managed to represent (i believe) the bolivian team because of some like really obscure connection he has to bolivia
(like it's not like "one of his parents is born there" or smth like that, it's like a very obscure connection lol)
so yeah lol
if you really wanted to do the IMO, i guess try to find a connection to like a country that doesn't perform so well lmao
anyway yeah that's what i heard from like the older uk olympiad ppl, u can find arran fernandez on the IMO website lol
hi what's the difference for qualifing for the BMO or the andrew jobbings kangaroo? cause i feel like its just made for schools that dont want to participate in BMO
wdym by difference?
BMO1 is harder, kangaroo is easier
Spain XD
We are so bad
math
yeah ofc but i was told by my school that even though i got gold in senior math challange they are not going to qualify me for bmo
i was just wondering if im being brushed off by the teachers
From which contest?
math
Ten points in the plane are given, with no three collinear. Four distinct segments joining pairs of these points are chosen at random, all such segments being equally likely. The probability that some three of the segments form a triangle whose vertices are among the ten given points is $m/n,$ where $m_{}$ and $n_{}$ are relatively prime positive integers. Find $m+n.$
check this out
fpoisonn
how long do you guys spend on a challenging problem before giving up?
Depends on the type of problem
As in contest or research
I’ve spent 1 year working on a physics problem
Or more but it was on/off
wait at that point it's more like a project tho right
Yeah
I never ended up implementing the full solution since it was more complicated than anticipated
dang
what about normal math problems
ones that should take around 3 minutes but you get stuck on forever
About 1h max
Depending on difficulty
If you are trying to study a new topic I would say 30mins
Unless you know it is supposed to be extremely long and hard
i see
@vague temple can you dm me??
Why
I need to ask you something
About?
You’re chinese right??
Yes
Yeah wanted to ask you smth
Ok
i need only the finest ppl to respond to this question
(anyone who got like a 130 or sum lol)
on 10b
or 10a
you guys recommend books?
my friend just told me to do a bunch of the practice tests
personally reading is cringe
i just do practice tests
brawl stars is better than math
Aops textbooks
it goes gold < kangaroo < olympiad
so even if u get gold, you'll need to score even higher to qualify for kangaroo/olympiad
if you qualify for olympiad but ur school don't let u do it that's a bit unfortunate
Can you join independently?
nah
I just use handouts that I find online
Textbooks mid
Yeah thats what probably happened
Might do next year
if ur off by a few marks, u can pay to get in to do BMO1
i know someone who paid to do BMO2 and did surprisingly well in BMO2 so they got invited to camps etc. after BMO2
i also know someone who did IMO for the UK who completely flopped BMO1 the next year ahaha so they paid to do BMO2
they didn't even meet BMO2 qual but they got 40/40 on BMO2 💀 💀 💀
thye are probably like one of the only ppl to score better on BMO2 than 1 (cus BMO1 is out of 60)
u can probably work out who they are if u look on the BMO1/2 leaderboards, there's really not that many 40/40s
