Best Calculator on the App Store!!

Exactly what I was looking for in a calculator for my Mac. It has a backspace key, something that ALL calculators on computers should have--the others are modeled after traditional calculators, which is completely asinine. I had been looking for the closest thing to CalcBot for the iPhone, and this is it! Well worth the $4.99. Thanks!
