- AmphibianTree 7y agoA long time ago, I worked for the HP Calculator support...made so many people happy by teaching them RPN. Most of the HP calculators had an RPN mode in the last few decades and they’d get stuck in it...a little 1, 2, +, 1,+ would be all the training wheels they’d need to understand RPN. Shame it’s not used more broadly. https://en.wikipedia.org/wiki/Reverse_Polish_notation https://en.wikipedia.org/wiki/Reverse_Polish_notation
