You know, that was totally me in elementary math. It was like it was so easy I spent a lot of time making it hard in my head. I did really mediocre in math in elementary school. Not to mention there was just this sub culture of "girls don't do math" at my small catholic school, nor was there was there anything resembling GT prgramming or identification there.

And I went on to get BS degrees in math and comp sci. I loved math once I got to algebra!
