this makes sense
I wish I'd had it explained to me like this in high school (and for the record I had an excellent math teacher when I first learned this, but it was treated more as trivia, and wasn't relevant directly to our material)
we did have a marching band/footbal cheer based on it though, and got a couple extra credit points for having our director vouch that we used it during games :P
