HP Prime - Parenthesis Play. Message #1 Posted by Chris Tvergard on 10 Oct 2013, 11:02 a.m. I'm going to be more careful using parentheses from now on. Edited: 10 Oct 2013, 11:21 a.m.

Re: HP Prime - Parenthesis Play. Message #2 Posted by Marcus von Cube, Germany on 10 Oct 2013, 12:12 p.m., in response to message #1 by Chris Tvergard 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! :-)
