In this case, your command is F1. In algebraic notation, you would enter F1(5) to get 25. In RPN notation, you would place 5 onto the stack, and type F1(1).

Ok thanks.

So if I define a function with X and Y, then I would enter Y and then X onto the stack, and then type F1(2) to tell it to use the last 2 entered parameters on the stack?

Yes, for a general 2-variable function. Usually, F1 is intended for a single-variable function.
