Screw factorizing specific numbers; do some introductory Analysis 1 homework:
Proof that every integer > 1 can be factored into primes, and that its unique (ignoring order)

(since its ana1 do it via induction please^^)

thats pretty easy, I think is the origin of number theory or smth idk

Its the Fundamental Theorem of Arithmetic

and yea it was 1/4th of our students homework after the second lecture in Ana1 while I was tutor (or a variation of it -> e.g. all even numbers, just so they cant google it... AI probs makes those efforts useless though)
its great for understanding how induction proofs work, but also then having them think about the problem after the induction (since that doesnt prove the order yet)

(that being said I wouldnt call it easy for Ana1 students at that point, cause those homework sheets were rough to grade)

u lucky he ran out of time, and also, im nobody to tell you this, but why dont you trade pieces, im only 1k elo and i trade pieces anytime in this game (the prolly wouldnt have come to a stage where pieces are tradeable anyways if i was playing)

#32

on 14th move i didnt trade cuz i rly didnt want to relinquish my bishop pair, 16th move i traded cuz i could win a pawn

18th move i played b5 but honestly i probably shouldnt have done that, my e4 pawn and the knight on the c3 were already unstable and having the lone pawn on b5 kinda made it vulnerable to future overload tactics

on 21st move i didnt want their bishop to take my knight cuz them my e4 pawns gonna be unprotected

25th move i probably shouldve traded my rook cuz rxc8 bxc8 and nd4 looks pretty hard to defend

a lot of them have been troll but here’s two fun ones, it’s not the greatest to bash but if you can figure something out then it gets easier

8365427
40081

first one i have no idea

2nd one looks like theres smth cuz its [(200)^2]+[(9)^2] but idk how to make progress from here

#36

the first one is (200 + 3)^3, you can see the binomial expansion if you look closer (8000000 + 360000 + 5400 + 27), so it factors into 203^3

the second one is called sophie germain factoring, if you have x^4 + 4y^4 you can factor it as (x^2 + 2xy + 2y^2)(x^2 - 2xy + 2y^2), so since 40081 is 3^4 + 4*10^4 you can plug in to get 149 x 269

I have forgotten Binomial expansion, but definitely learnt something new in the 2nd one. W nataliee!

lol, ok, I'll read some. Don't think it'll get much attention though. Aren't most of them lengthy?

nah most of them are pretty chill tbh

like for example the area of a given circle is log₁₀([100!]²). find the radius of the circle to the nearest tenth

american curriculum is crazy wtf is sophie germain factoring

the only germain I know was PSG XD.
I don't think this factorization is taught though, wasn't taught in India

it's olympiad toolset, similar to things like the am-gm inequality

AM GM is taught in schools no? that’s just a basic geometric proof that takes like 10 minutes lol

most students can state the inequality just fine but can't use it to solve problems. most factorization tricks are also introduced to kids through problems that the students never get to go over except u frequent aops or something

ahh fair enough, i go to aops just to look at past amc12/aime problems but i dont chat there or anything

it’s not standard school curriculum lmao i’m an AIME qualifier and i study competitive math so i know a lot of math way outside of the typical line of study :3
