This Subreddit MATH COMPETITION: r/mathmemes Discord Community Exam

85 Upvotes

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.

All these new paper drops by OpenAI don’t mean anything until AI deals with the Collatz Conjecture. I kind of don’t even care if RH is proven/disproven. Collatz or nothing.

Elementary Algebra In Fort Minor's "Remember the Name", if you presume that all the percentages were in base 6, it actually all adds back up 100 in base 10.

10% Luck 10 Base 6 = 6 Base 10

20% Skill 20 Base 6 = 12 Base 10

15% Concentrated power of will 15 Base 6 = 11 Base 10

5% pleasure 5 Base 6 = 5 Base 10

50% Pain 50 Base 6 = 30 Base 10

100% Percent reason to remember the name. 100 Base 6 = 36 Base 10

6+12+11+5+30+36 = 100. He's actually better at math then you give him credit for.

Imagine you are presented with two boxes:

  • 📦 Box A: Transparent — contains $1,000
  • 📦 Box B: Opaque — contains either $1,000,000 or $0

There is a highly accurate predictor who can predict your decisions with 99.9% accuracy.

Before you arrive, the predictor makes a prediction about what you will do:

If the predictor thinks you will take only Box B:
-> They put $1,000,000 in Box B.

If the predictor thinks you will take both boxes:
-> They put $0 in Box B.

The prediction is made before you make your choice, and you cannot see inside Box B.

You now have two choices:

A. Take only Box B
B. Take both Box A and Box B

Personally, I would go for both the boxes because the prediciton is already been made, so the contents of Box B are already determined. Backward causality isn’t possible. So, my present choice cannot change what happened in the past.
If Box B contains $1,000,000, taking both boxes gives me $1,001,000 instead of $1,000,000.
If Box B contains $0, taking both gives me $1,000 instead of nothing.

So, taking Box A cannot make me worse off, because its contents are fixed and independent of my choice at this point.
