Really nice ! Just the variable are every time changed from inside the sketch. Also there's people who added a keypad as a calculator but do you have any idea how can we insert a and b from outside. Because keypads can text only single numbers from 0 to 9. What if we want to insert a = 18 and b = 245 ?
