I need help figuring this out in java. All I have so far is the buttons for numbers 0-9. I'm not sure how to add, subtract, or basically get them to do anything besides show up on the frame. Anytime I try to add any functionality to the buttons, the whole thing just falls apart and results in errors all over. Please help, or at least guide me in the right direction, I'd really appreciate it!

The original problem:

Create a GUI Calculator with the standard functionality of addition, subtraction, multiplication and division. You calculator should also have the additional functionality of sine, cosine, tangent, square, cube, raise to x to the power of y, and square root.

Your calculator should also have a memory button, memory recall button, and clear. The calculation should be displayed in a text field or text area based on your design.
