Btw, when I'm going back to school, having about percent and total, I'll outsmart my techer

She doesn't accept *0.percent even o.O She instist it is The total*Percent/100, which is much a much longer(yet the same) formula, maybe easier to use without calculator, but who cares?

And finding the total is much harder, infacrt I always forget the formula she gives away o.O
