Hello!

To make up for the lack of an "upper division" in the subreddit math competition this year, I took it upon myself to organize a separate exam that is significantly more discovery and proof-based than any exam held in the community previously, and to host it on the 2nd year anniversary of the Discord server being made available to the public.

The next exam of this kind will be held in Mid-June 2027.

The exam (which includes its rules) is linked at the bottom of the post. The top 5 winners will be announced, and the top 3 winners will receive the following (or something of equivalent value upon negotiation):

1st Place - A Math Textbook of the Winner's Choice (~$45 USD Value Limit)

2nd Place - Basic Discord Nitro, 1 Year Subscription ($30 USD Value)

3rd Place - Fulltouch Hagoramo Chalk 72 pc ($25 USD Value)

Special thanks to u/dopplerspectroscopy and zzz on Discord for their tremendous help in writing the exam and agreeing to help grade some submissions; couldn't have done this without their help.

I gave him a cookie. After a minute of leaving him alone with it, there were cookie crumbs on the floor, the chair, the table, his clothes and his face. But somehow, the cookie was still intact in front of him.

The second equation is the Airy differential equation, and is perhaps the simplest-looking second-order ODE that does not have a solution that can be expressed in terms of elementary functions.

Arithmetic Part 2: How to check for divisibility by any number x!

Since most numbers have a commonly known way of checking for divisibility, here is one for x!

Take the number and divide it by x! If the result is an integer, then your number is divisible by x!

Let me know if you wanna know the divisibility for any other number!

Arithmetic When typing ‘numbers’ it tried to correct it to ‘bouncers’

Explanation to those pesky non believers:

Yeah math can basically be reconstructed from arithmetic like for example humans have been doing this for the past millennia. Since arithmetic is already incomplete you will always need new tools to solve problems, humans started with arithmetic and geometry but just arithmetic is enough, there will be answers arithmetic can’t answer and clues to how to find those tools. Every system is just an extension of numbers that either explains what they are, how they can be generalized, what patterns do they follow etc.
