By the way, how fully-featured and functional is RPN on the HP-Prime?

Is RPN viable and marketable? I would say yes, because based on this monstrous "common core" analysis of how to subtract one number from another -- rather than enter one number, then the second, then hit the minus key, we have a convoluted mess. See: http://thetruthwins.com/archives/you-won...ubtraction (it's probably been pasted here before) But somewhere, someone in America decided to make it harder..... oh, what a silly act that was.
