For any interesting observations, proofs, or problems you discover on your own, post them here. It doesn't matter if you can't post every week, as long as you're working on something.

Examples:

Interesting competition math problems you solved

Things you want to explain about math so you can understand them better

Random things you saw in Pascal's Triangle while taking a shit

Solving Riemann's Hypothesis... while taking a shit

etc.

You can discuss stuff in the Discussion Board. There are no rules here, as long as you don't steal someone else's math and post it as you're own.

If you can use LaTex or MathJax for formal-er stuff, that would be nice.
