i know there's a few maths nerds among us from the numerous formula threads that have popped up so i thought i'd share this website with you all.

very difficult maths problems that are designed so that you have to write a computer program to solve them. i've only solved 14 so far. very very hard...

Seriously, I was clicking around and couldn't see anywhere to submit the answer to the first question. Every other question seems to have an answer box for which I can submit answers, though.

This looks fun. The ones near the top seem like just a matter of implementing a basic program. I'm going to scroll down and look for ones that require more figuring out on your part.

And I can barely wrap my head around what's being asked in the ones near the bottom. Maybe I'll come back to this in the summer when I have no homework.
