Below is what should be the finished code. I even added a clear button.

That should be it. I still am working on positioning, but maybe you can do that to help yourself. The error was extremely embarrassing, but a typical one. Below is where it was, I just copied the first one and pasted it for the next three if statements, without changing the operation. Basically they all divided so when I was clicking multiply in the program it was dividing, it confused the hell out of me, haha. if(operation == 1) display.setText("" + (first / Double.parseDouble(display.getText()))); if(operation == 2) display.setText("" + (first - Double.parseDouble(display.getText()))); if(operation == 3) display.setText("" + (first + Double.parseDouble(display.getText()))); if(operation == 4) display.setText("" + (first * Double.parseDouble(display.getText())));
