    What happens when you press it?

    If there's an expression on the screen, pressing the x^2 should put a superscript-2 on that expression (or the last term thereof). If there is no expression, it will use Ans.

    For example, starting with a clear screen, pressing 3 x^2 ENTER should produce 9. What happens on yours?
