Crazy Calculator 0.0.7

for Doopro P2

The calculator is very simple, with the four basic operations. What makes it different is the ability to play with friends who ask to borrow a calculator.

The number buttons (0-9) and operations (+, -, * e /) change places from time to time, leaving the user crazy!

If you want to return the numbers to the right place, just shake your device they return to the place (but come back to trade places with use).
