I'd first try something simpler like a four operation calculator. In this calculator, there's two number fields and a button for each operation: "+-*/". Each of those buttons evaluates the respective operation for the two operands (extracted from the two number fields).

Do you mean a standard one that gets 2 numbers from text boxes, or input boxes? I can do that w/ sq roots added. So each button does one function, that was what i thought. You need to use advances stuff to do functions by pressing 1 and then - and then 2 and then =? Thanks, i'll try to keep learning.

Shoot, I didn't even notice that. That's neither a calculator nor a telephone keyboard. Something like this, for simplicity, and drop the memory functions.

If you're at the skill level you say you are, and assuming you still decide to take this on, I think it'd be easier to use a stack for evaluation instead of an expression tree.

In my opinion, a stack is an easier data structure to grasp/use, espescially if you're just starting out.

Ya, that's what a walkthrough on rpn said to do.
