quick vb question

[markjrubin]

I'm working on a calculator for class and I'm a little stuck on the +/- button (turn number to negative if positive, turn to positive if negative). Is there a numerical function to do this or will I have to do it with string manipulation?

Don't use a string, keep it numeric. I would make a little function that takes the value and doubles it and then subtracts it from it self. And then vise versa

well that makes sense
