Who I am
I'm a mathematics major at Ohio University.

Things I've learned about Wikipedia/Wikiversity

 * I didn't think that Wikipedia would encourage |bold edits to the extent that they do.
 * |"Wiki" means "quick" in Hawaiian.
 * I didn't know that Wikipedia had a sense of humor. Intentional or not, "In general, 'that is a terrible idea' is always sufficient grounds to avoid doing something, provided there is a good reason that the idea is terrible." is a funny sentence.
 * I didn't know that Wikiversity existed.
 * I didn't know that the editing commands for wikis were so easy to learn.

Vandermonde's Identity

 * $${m+n \choose r}=\sum_{k=0}^r{m \choose k}{n \choose r-k},\qquad m,n,r\in\mathbb{N}_0,$$

Code for displaying Vandermonde's Identity from Wikipedia.
