it says "ans *" rather than 81

I hate to send it back to Amazon. Is there any way to get it to behave

It seems that you're obviously not in RPN mode. Confirm your setting. <Shift><Home> opens your setup screen. There you chose the "Entry" mode, select "RPN" and you should be done. But ensure to switch the calculator off <Shift><On> to store the status in flash memory rather than only in RAM. Otherwise any reboot of the PRIME would disregard your previous settings.
