this is my first Android app. when i got my android phone there really wasn't a decent general purpose scientific-ish calculator available. being a turbo-nerd i find it very convenient to be able to compute expressions like 25-37+2*(1.22+cos(5))*sin(5)*2+5%2*3*sqrt(5+2) wherever i go. according to LeCalc, the answer is -9.8
