IntegerPlusMinusCalculator is a calculator that can be used to experiment with calculations of mathematical expressions such as +605+6-18+5, -75-8+3 and --9.

Unlike other calculator apps it is focused on teaching about how to best look at a sum of (plus and minus) terms. Therefore a plus sign is automatically put in front of the first number unless it is negative.
