What is an RPN Calculator? In a nutshell: Instead of entering "3 + 4 =", you enter "3 4 +". With RPN, you don't need parenthesis. It's very efficient for doing complex calculations. Once you get used to RPN, you won't ever want to go back.

Disclaimer: YarrRPN Calculator has nothing to do with pirates. If you buy this expecting pirate stuff, you will be unhappy. It's a serious calculator app with not-so-serious name.

Ahoy!
