HP Prime - Parenthesis Play.



#3

I'm going to be more careful using parentheses from now on.

#4

Chris, this looks perfectly correct to me. Exponentiation is associative from right to left. The question is, how did you enter the expressions?

2 xy 2 xy 2 xy 2

returns your first example, while

2 x2 x2 x2

returns the second.

To avoid ambiguity stick with RPN! :-)
