[TIPS] History of Math symbols

I think I found this in the Math tag at del.icio.us. Its a site that tells the history of math symbols. For example, I think I read that the right parenthesis was first used for division. I'd better stop there, as I did only briefly read over it.

But, share that one wtih your math teachers. Little bits of trivia to put at the bottoms of test pages, etc.
