Who would have guessed an ENTER key would be considered a frilly, unnecessary key on an RPN calculator?

You just have to clear the calculator and press + after the first entry. After all, it only has a two-level stack! I wouldn't want to use it now but it was a help back in the day, I'm sure. I don't know about the utility of a divide key on an integer-only calculator, though.
