Eventually you can add something to this so that it distinguishes the operators separately and the user can write an expression rather than answer questions about the expression, I think that is really the goal right? I hope you find the comments below useful as you progress. You do this in multiple places. This is my first attempt at using methods and would like to see if I can improve on this as there is a lot of repeated code. Some other small things You should consider using a switch statement on your choice variable: switch choice { case 1: performAddition ; break; case 2: performSubtraction ; break; case 3: performDivision ; break; case 4: performMultiplication ; break; default: System.
