my school doesn't have IB but we have a course called IB math that u can choose for like a year
idk how that works
oh
it’s a french school
we have like these igs
and u can choose to take one as a math course in 11th/12th
but they seem kinda boring
gg
ik
thats why i looked over it read thru the course descriptions went hell nah
id rather take bc then ts
bru how 'abstract' can school math be
bro ikr
like holy bro, "intellectually equipped to appreciate..."
ik
ts is so sad
"Throughout the course students are encouraged to take a considered approach to various mathematical activities and to explore different mathematical ideas. " wdym a considered approach 💀
nahh the only mathematical activity ima do is quitting that course bruh
gg
oh wherer you?
bruh everyone is est or pst nowadays
guys im not liking the aops books, are there any videos that teach amc maa/ teach concepts in aops books?
Same
thats amazing
anyone here knows abt ioqm?
Um, did you clear that with the <@&268886789983436800>?
idk
same
theyre too tedious
and I’m not patient enough
Yes
How is IOQM computational? I don't think so it is
Its not a proof round
Its just short answers
And easier questions
That qualified as comp imo
Easy for you dude, you can't understand how it's like to be average
hi zelix
real
hi
ook
Hi zelix
hi curiousgorilla
hi brian
hmmm
Halloa hru friend?
im saying relatively
compared to INMO
you don't understand how bad you have to be to be 'average'
oh
?
In math
real
yess
hmmm
Hi
hello
hi other friend
hello unc
hi older unc
i’m like three years younger than you
zelix=orz
my birthday hasn’t passed
dawfid orz
All orz
oh
Halloa unc
Hi uncer
SOOO old wtf
ye zelix
You cant be talking
Youre like a month more ancient
i'm 2
unc
ook
1932?
oh 1831
unc
wait what year are u born? 12
or 13
13
yeah sooooooo old
im hoping you are born in april or earlier😭
ye i was lol
me too
halloa friend
hi friend
Wait, how are you class of 2030 then if you are in 7th grade??
Right now is ‘class of 2026,’ and if you are in 7th rn, you have 5 more years to go. 2026 + 5 = 2031
How do u know that I’m class of 26
Yea
you’re a senior?
Yes
oh damn
so unc
thats literally my birthday
what grade are you even in
8th?
unc grade
atp >5 months old is unc
middle school ppl are big
i saw that ):
cap
my grade is tiny
except for a few outliers
im 5 4🫠
i have a fruend whose 6 3
im tiny😭
5'4 = big
cap
the least unc grade possible
0.67
u are not 4'4.7
ur tall
signs of unc
i am 13
im 889
how tall are you?
sure
read message history
i’ve legit proved it
lazy
5 4
where
so 162
4th grade
i can prove im 13
ik wha a line is
are you french????
i go to a french school
ur tall
thank you
Hello. This problem here got me stuck as Idk where to start. I don’t want to look at the solution, but may someone please drop a hint?
in a tall french county in a tall french state in a tall french country in a tall french world
thanks
That’s pretty tall. Lowkey, don’t know how tall I am. Haven’t checked in a long while
uhm idk how to solve diophantine
but ig
u should check lol
x and y are interchangeable, meaning the solutions where x and y are different can be paired together bc of symmetry and swapping
i had to give all my measurements for a sports thing yesterday so everything’s all accurate now
so really, the number of solutions where x=y has to be odd too
I mean, I am just super braindead rn, so I might just check back in tomorrow and I’ll probably do it. Will appreciate any hints or ideas, though
what state r u?
ok fine ill stay awake for a minute or mybe
ik mila ks cali right
who
u
Lol, I’ll check rn. I have a measuring tape
k bye if i sleep now ill only get 7 and a half hours
so you’re also est?
cleveland suburbs
alright goodbye
I am like 172,75 , basically 173 Ig
I thought I was shorter tbh
ooo wow you’re also tall
I haven’t checked my height in such a while, I’ve grown wth
i grew 17 cm in like nine months 😭
uncville
What 😭 I only had a growth spurt like that when I was like 10
Or if u want rigour
Thanks
i think they meant youtube channel
the best way to learn is to do a bunch of derivatives
just get spivak and stewarts and do all probllems
bprp
Noted sir
aops if u wanna do comp math
guys i have purple comet maths comp tmrw, does anyone have any recommendations for concepts i shld learn or go over. im in year 10 doing gcses, but these question are a level difficulty i think
looks pretty similar to amc10
Professor Leonard on YT. Not really competition math, but you said derivatives soo for books—any calculus textbook would work. I recommend Seeley’s Calculus of One Variable and Spivak, but any calculus textbook you can get your hands on would do
i heard about it 3 weeks ago 🤣
You heard about it 3 weeks ago and are only now—one day before the competition—starting to study concepts for it?
Or have you already been studying up? What concepts have you went over so far? Did you do some past papers? That’s the best way to prep for any competition
Just do past papers
im not really taking this seriously cs we hv kangaroo maths in may
Any other tutor ...like on yt
I am not the best person to come to for lectures on YT. On YT I mostly watch physics or ways people solve problems. The only channel I’ve used for calculus on YT is Prof. Leonard, and he’s great imo
Sooo other people can offer some help with that
Np))
Oh, also—I’ve watched some calculus videos from Michael Penn. Check him out @iron mason
He has some nice problems
I more watched his proof-writing and nt videos, but I am pretty sure he has a ton on calculus as well
Js do past papers
And sum amc past papers as well
Idk I’m doing purple comet too and that’s what I’m doing
To be fair I’ve been doing amc related prep for a bit
But I still think it helps
Khan lwk goated
its the opposite time of the year from amc bruh
Yeah but I have other math comps
And during thr amc time of the year I don’t have time
Cuz I have a bunch more comps
Best time to start prepping for the next AMC
it is?
Well, why not? It’s best to have a lot of time rather than only like one month
I personally don’t like only starting to prep for something a month away
ye it's never too early to prep
if i prep for aime
cuz its x20 points
then i'm also prepping for amc technically
r u
but reading pirated egmo is like prepping for amo
uhh
So you’re saying AMC doesn’t need almost any prep at all? To get into the AIME you first need to score exceptionally at the AMC
Technically, Ig
a bit
a few months
before amc
shush patrick
Okay well not everyone is at such a level that they can get top scores in the AMC by prepping only like two months
Plus, some people are faster in that regard, some are not
Better to start early than late
ig
Deca states
No
Deca regionals I think
Model un state conference
Sci oly comps
And I’m gonna be working on shm other projects as well
ye

yes sir
we will go back on topic
i like tren
hey guys generic guy wanting to do amc, how do i prep for this (im in calc ab rn but i have no experience with competition math so im probably weak in stuff like number theory)
is there like some specific resource or website that i should use
for a website i'd recommend aops
and for books if ur prepping for amc 10 then i recommend u get aops vol 2
amc 12
ye vol 2 works for that 2
if u want to work on a specific area then look into the topic specific books
alr
Or awesomemath l1
BITC
aops trust
I do not have the money for AoPS books either — sad that there are no free online versions
I sometimes take AoPS textbooks from the library but I need to bring them back within just a few weeks, which does not allow for much learning
ikr
euclidian geo in mathematical olympiads
written by the goat, evan chen
more useful for learning abt proof-writing skills tbh
hm
aops has some fun problems my friend said
so i will attempt to borrow it from him
ts expensive asf
wish i decided to do amc earlier bc now i only have one shot
oh well ill cook (probably)
u doin amc10?
no 12 im going into junior yr next year
oh ok
there’s a pirated version online
actually maybe don’t do that
i tried finding one
i’m definitely getting a virus
oh well it’s a school computer
Yeah no, will not risk my laptop
There’s some really sketchy sites that claim they have math textbook pdfs
perhaps we just pay the $50
no
@little wraith @olive haven i have nonvirus copies
if uw ant them
of most common olympiad texts

does anyone know anything about math kangaroo?? 9-10
im having problems grasping these questions
it’s a big thing in france for some reason so my french math teacher makes us do them weekly
hmmmm
p np will be our final problem on our tournament trust
any resources on olympiad training?
aops books
they are useful for learning problem solving methods
yall in school we had a math olypian and i got the top score, there will be another test on sunday how do i perpare
hello li
what test is it?
patrick li
❤️
@inland totem

olypiad
im doing olypiad too
cool
Your math teacher at school teaches olympiad math? What type of school is this 💔
Do you go to some specialized (for math) private school?
i wish. it’s a private school and idk what’s he doing but he just gives us a kangaroo sheet and has us do it in pairs but no one really takes it seriously
At least its better than my old school. I remember doing the amcs in 4th grade, and everyone (but me) did it in pairs (it was official 😭 )
you can do the amc in pairs?
i've always took it in testing centers
Now I only take it at rsm
Except for the amc8 in 5th grade, but that was a lot better
ok
🦧
The AMCs in 4th grade???? What type of schools do y’all go to wtf 😭
I js randomly wanted to do amcs because my sister did them
😭
Ohh, just as a proctoring place. I thought you meant the school has people take the AMCs in 4th 😭 😭 Nvm
lmao
Hi
Hello. I wanted to ask: What resources are there (except AoPS) for elementary olympiad combinatorics? I am planning to do the AMC (never taken it before), and I can confidently do around 9-17 problems (depends on the past paper), but I always get stuck with combinatorics questions. I’ve learned some of combinatorics before, but I have really bad gaps in my knowledge
I don’t need a book focusing solely on problems, I have a ton of those, I just want a resource that can explain the topics clearly
wait did anyone else take course aux nombres
it’s a mental math completions
nine minutes for thirty problems
Isn’t that French? Or is it something someone can take from another country?
like
what parts of combi
are you stuck on
Most.. I just need an overall combinatorics textbook, starting from complete basics. I never really formally studied combinatorics, all my knowledge is from “here and there”
it’s french but it can be taken anywhere i took it in th US
theres a website someone made called saintly thats pretty good, and it sorts by topic so im pretty sure theres a combinatorics section
Skimmed through it. So far I only see that there are past paper problems. I am looking for something a bit different. I need a textbook or some kind of other resource (ex. lectures on YT) that can explain the topics of combinatorics. I already have a ton of resources with olympiad problems, combinatorics included. But thank you, this might come handy as well
Hi
The Measurement Problem as a Category Error: A Mathematical Proof of Wavefunction Unobservability
This paper is a mathematical proof that wavefunction realism is a category error, with direct implications for how quantum mechanics should be interpreted and tested.
https://zenodo.org/records/19630890
We prove rigorously that the quantum mechanical wavefunction ψ is mathematically unobservable using information theory, set theory, and Hilbert space analysis. The proof establishes quantitative bounds: reconstruction error scales as ∥ψ − ψ̃_N∥² ≥ C/N² due to the uncertainty principle, making exact recovery impossible with finite m...

Halloa!!!
SUCH a good question
Unlucky, come back later
(This pinged, by the way).
Again, everyone please go to #discussion or #chill or people will continue to be muted
will u be the next mute?
Bruh are there any good math comps in california
Oh my bad
And that one too.
u could search on google
Too lazy 🥀
but the first one that comes to my mind is berkely math tournament
Oh shi I've been there
Is it actually prestigious
Most prestigious one is bkmc
i'm pretty sure ye

Okay sorry
I just do short off topic chat
jesus what in the math compeitions is this
so on topic
its the plen likes wen theorum
which has been proven false
where is ur rigorous proof
Naturally exists
the riemann hypothesis is true because i say so ahh
Indeed it is true
React to this if you like wen
god tier ragebait
Now i have two rigorous proofs
alr on topic now
Yes
FU
FU
they aint abt anyone yk anyways
so then if i murder some random its fine
cuz theyre not someone you know
Ts logic is fire
i said you dont know theres thousands of ppl in the world
its just wrong in general
and kinda weird
buddy u dont even know whats happening 😭
whats happening
and dont buddy me
ok nvm
ts weird asl
lmao
smth definetely happened thats for sure
First to speak is me on apr 18, 2026
thanks for admitting
saying that to the carbonite 💔
not comp math
why is everybodyvadding gcant to their bio
idk
hmm
what
dw abt it
ts is so tuff
fr
omg so tuff
is this ragebait
i can feel resentment from this
uhh

buh what
ook
React to my previous message if you like wen
With ook specifically
i forgor
React to this if you like wen
say "React to this if you like wen" if you like men
no point
i already have many rigorous proofs
what in the comp math
feels weird saying that when im 13 now 
too orz to comprehend
the thing is, ragebait is fun only when you do it correctly
this just isnt it my guy
have a great day tho

basically you just admitted this isnt fun
so your annoyed
so your being ragebaited correctly
im not annoyed, im carbonite
i think you need to use duolingo
omg ur actually so tuff
finally unbanned
I have!!!
hi zelix
hi gorilla
I guess you didn't listen to the warning. You have some other tickets so we're gonna go with a long mute. Behave better after the mute expires.
The prev message applies to you as well given that you are continuing the same behavior that caused your last mute.
wait what did zelix do again
Rip zelix
Bruh he replied to the wrong message
I think he meant to reply to the bmt one
Bc we went to bmt together
You complaining about this is also off topic. Keep it on topic.
dumbass mod
7 day banning for like no reason
js had to put that out there
Congrats you get a free mute too. Go figure if users accumulate warnings, tickets and mutes for the same poor behavior we escalate to longer mutes. Wild stuff.
damn so many ppl are muted that the entire channels gone quiet
ye cuz for some reason someone gave this guy mod
banning for 7 days cuz of some "I have" shit
zelix u look different
but i don't think mute evading is the rigt approach
ye, fried moderation
Ok, just to be clear, anyone who continues to use this channel for off topic conversation will also be muted
Hi. Asking again, does anyone know any good resources to learn combinatorics topics? Would be preferred if it goes from the complete basics but still has a solid kind-of-olympiad level. I just have gaps in my combinatorics knowledge that I’d like to fill. Thank you!
You’ve all been more than fairly warned
what level
What is even going on here? Is it that hard to keep things on topic? Just go to lounge 🥲
honestly its rly just aops for me
it's always been like this
hi
You might also have some luck in #book-recommendations , I think I’ve seen people talk about the art of problem solving books for things like this, but neither combinatorics or competition maths are really my thing
then theres the books on specific topics
Sorry, forgot to say “except AoPS”
aw
nooo
I am too broke for AoPS books
Okay, thank you!))
I’ll check in there in a bit
I’ll look into that. Thanks
halloa!!!!!
Found a pdf. Quickly skimmed through and it actually looks like something that would fit me. Thank you!
np
if they made a preuni lounge it would be better
be so fr who wants to hang out with a bunch of adults
theres a lot of university papers and resources explaining certain topics
all u have to do is search it up
although some may be really hard
yess
hmm

guys is it normal to take amc 10 in 9th
or should i take 12 or just wait
bc i took a 'mock' amc10 test with a timer on myself and got 23
so should i take 12 next yr?
whatd aops do
oh nvm
yea
ver expense
but imo its worth it
kinda
bc it gives u everyth u need
even tho it costs as much as my house
yes
okie ty
Why would it not be normal?? I’d say go for AMC 10
If you’re confident with AMC 10, take AMC 10
lol
But if you want challenge, take AMC 12 yeah
ive just never taken amc b4 so idk
ty
also im just about to start calc but im in the indian ciricullum so like everything ik is from aops and idk when to start calc, but im familiar with algebra geo combi and NT so should i start calc or wait
for depth
I mean, it depends on your interests and goals
If olympiads are the goal, you can wait on calculus Ig and focus on olympiads
yea
i mean my main focus rn is getting into a good enough college then start learning more math
so olympiads rn are my main focus
But at the same time, I personally study math for my love and interest for it, and depth is still super important for me, but it’s interesting to go a bit ahead (for example look into calculus)
asw as ap courses if i can afford
yea same but i feel kinda pushed to go fast so i can take a calc course in 9th
and do some physics bc acc physics is locked behind calc
for the most part
high school is like the only time you can focus on olympiads so tbh there's an argument for delaying calc and diving deep into olympiads
Same. I want to go deep into calculus because I want to go deep into physics, and without calculus that is almost not possible
but might only make sense if you're like decently competitive at a national level
That’s true
indias kinda cooked so i am
i'm not as familiar with the indian education system, but do you also have to take JEE?
because i thought calc was also part of that
or is that like only for some people
in the US probably most kids strong enough to participate in olympiads just do AP Calc BC in a year anyway since colleges know what it is and it's probably a straight forward class for them in most schools and they can focus on olympiad pre in their own time
yea my school is a verified ap test center so im taking ap calc bc
When? In 9th grade??
JEE is this entrance exam for the best indian college(IIT). Basically theres no application u have to send like harvard or anyth, but the entrance exam is hard asf
it has chem physics and math
my dad got 200 all india rank on the exam
(AIR)
out of millions of participants
yea
How 😭 Do you take like a placement test?
so no u dont hv to take JEE but most ppl do
basically im taking this course for AP calc BC in the summer of this yr for me(im in an international board ciriculum so the summer break is the same as the american one) and then i test for it in like june 2027
or smth like tht
the test is scored on 5 but im not familiar either
i will take JEE and calc is part of tht for the physics and math sections so im locking in on tht
i scrolled up to look at your original question and if you think you'll do really well on the AMC 10 but have never taken either is there any possibility of doing something like 10A and 12B?
Okay so you’re taking the course at school or outside of school? Because I keep having troubles with schools about this topic. Literally no school that I’ve ever went to could give me a placement test for some reason 😭
maybe
inside my school
im lucky tht my school teaches
its one of like 20 schools across india tht does
Well, you’re super lucky your school is so open to that
yea ikr
but if ur in the US u can prolly drive to sum school thts like 1 hr away to take a test
For students considering studying outside their home country, AP can serve as a global credential.
I am in the US, in California, but no school here, unless it’s like Proof school or one of the other bests, wants to give a freaking placement test and place me in the correct math class. At this point I like gave up
Yeah, makes sense. I’ll probably just take the AP exam without taking the class (you can do that, I think)
yes u can
Probably what I am gonna do
im thinking abt taking an aops calc course or the book and then test instead of the course
bc the math teachers at my school r stupid
I think just taking the exam is pretty convenient
But if you have the ability to, take the course
aops calc would be a good course, it's too bad there are so few schools that use it as an actual textbook for a year long course
222USD
yea
yeah taking any course through aops can be pricy
I mean the school course
AoPS is expensive
thats a good one, i read that in high school and it was nice
yea
the school course is 222USD
or smth
idk exchange rates
Wait what- why
but for me thts expensive
theres something to be said for having the course on your transcript but then you kinda have to put up with whatever quality your particular institution can offer
INR to USD
yea
my institution is not very smart
i think ill self teach better
and take the test
Okay, but at least they allow you to take the course in 9th grade 🥲
do you have an option to speed run an online version of a prereq over summer
sometimes schools will give credit for that and then put you in the right class even if they wont recognize anything else
Like take a course like pre-calculus?
like its hard to not put a 9th grader in calc if you take precalc over summer
yeah
just like ask them now if theres any online precalc theyd accept before summer starts
my precalc book is the same as an algebra and geo book combined so im not doing it
then if you're ready for calc it would be easy to just speedrun it over summer
here in the US there's a whole year's class between intermediate algebra/algebra 2 and calc
where you do like trig and complex numbers and stuff
Like at the school? Maybe I’ll ask. But outside of school, formal courses are super expensive
yeah like at whatever school you're going to, ask if there's any online precalcs they would take for credit. some might be affordable?
whattt
obviously it depends on your situation but if it saves you a whole year something to look into
for us in india weve been doing trig for 2 damn years
oh yeah here we just cram it all in precalc lol
we dont even do calc in our school
Sure, I’ll try that. I am in an online school (which is not private), so maybe I can even complete some kind of course of theirs on pre-calc
nor actual physics
@pallid heath Thank you!
Wait but you said you can take calc in 9th??
i did something like that and did algebra 2 into precalc online over summer into ap calc the next year
that actually sucks
For real
the ap calc course
not in the normal ciricullum
i hate my ciricullum i hv to pay so much for extra stuff
I mean, calculus here in the US is not usually the normal curriculum either
bc my school is stupid
yea but at least u hv problem solving and go in depth
our school doesnt teach what a function is
😭
Okay, that depends on the school
good point
Like the schools I’ve been to were not in depth in any way
most schools everywhere arent lol
Yeah lol
but theres just a huge range, especially in the US, so the best ones are great, but the worst can be so so bad lol
Unless it is some specialized school for math kids
but my school is like damn expensive
oh btw i used to live in cali asw then moved
i went to a public school
here im private but thts js useless
i would rather go to sum public school here
Okay but here in Cali it depends on the region and town
Like in some pretty rich towns, the public schools are way better than private schools in other towns
i live in the most tech dense place in india
basically silicon valley of india
in prolly the 2nd most reputed school here
and it sucks
but in cali i get tht
Well, schools can never give you complete depth. They focus on a ton of students at once and the students are at different levels
yea
You can’t expect a school to teach you olympiad level math. If you want to know math deeply, you have to self-study
