Just click on what you want. The ^ is shift, and if you press it and then <- it will clear the line. Without shift, <- deletes the previous character. Press the weird symbol with lines to get + and -. **Keep in mind that you have to press on the actual character to have it register. For example if you click in the middle of the 0, it will not register.
This is the most basic calculator. It only has addition and subtraction. I am planning to add more in the future, and possibly even make it do some crazy things, like graph. IMPORTANT "x" does not work. It will only confuse the calculator.
