...it means that the other number is cubed, or multiplied by itself twice.
53 = 5 X 5 X 5 = 125
Pie

T over 3 could mean T divided my 3
Almost everybody. I mean, I'm pretty sure the answer is supposed to be "Albert Einstein" or someone like that, but really, who cares? What math means when you're a "little kid" is basic arithmetic, which has very little to do with what "math" means at a college level.
