my roomie is just learning the product rule in calc--never having taken a calculus class before--and wasn't quite getting it. so i went over and figured out the f(x)*g(x) = [f(x)*g'(x) + f'(x)*g(x)], and i worked through the whole problem and suddenly thought, hey. this is fun. i miss math.

i miss math.

who'dve thought it?
