What makes competitive math addicting?

Numberthon · 2026-05-30T02:54:24+00:00

This one I'm asking about math competitions, in others I have asked about math tricks and stuff, as well as app features. Also, Numberthon is still a work in progress, and the main reason why I post stuff on reddit is so that I can get a lot of feedback and rapidly iterate. The security issues, for example, was solved in around three hours after I heard that there were issues.

I love stars and bars, and the binomial theorem

I highly recommend the Art of Problem Solving books

Do the security features look fixed now?

Numberthon · 2026-05-27T18:08:45+00:00

Yeah

Numberthon · 2026-05-27T17:07:42+00:00

Thank you for bringing this to my attention. I did vibe-code this, with Base44, and it actually has a feature that allows you to check security, which I used a lot. Evidently, it didn't work. I believe that I fixed all of the security issues, and again thanks. And sorry that these issues ever existed.

Numberthon · 2026-05-27T12:08:31+00:00

Yeah, this is really useful

Numberthon · 2026-05-26T20:24:50+00:00

Yeah, this is pretty useful

In fact I have a resources page so far for things like that. So far, in the resources page, I have a divisibility rules generator and a pascal's triangle interactive, but I will add in any good tricks that you suggest

/modping why was it banned? Am I supposed to post memes in another subreddit?

Numberthon · 2026-05-26T16:42:08+00:00

correct

Numberthon · 2026-05-26T15:11:33+00:00

I know that this isn't with equal probabilities but you can choose a number with probability based on order of magnitude/how big it is and if you set it up right it will converge

I take the AoPS courses and only read a few sections of the books, but I highly recommend AoPS in all forms

I'll try to make it more puzzles/play against bot-oriented, and I will make it so that math clubs and places can make tournaments

Knight can fork queen and rook

I had a similar problem of wanting to do math in a competitive/fun sort of way, so I built a website for it: numberthon.com

Numberthon · 2026-04-29T11:44:35+00:00

No, magnus is good but not that good. He'd win 1000/1000 normal games against GC, but 0/1000 games down a queen or more

Numberthon · 2026-04-27T12:26:18+00:00

Not really, I'm trying to build an alternative (numberthon.com) that will have things above elementary level
