Is RPN still relevant?

This! Years ago, I told a relative of mine that I preferred RPN calculators. He made a crude joke, saying it was called Reverse Polish Notation because it was backwards and stupid. I told him that it was neither. I said that RPN made it easy to solve problems in the order that we actually solved them ourselves, as opposed to the way the formula was written on paper. But also, since I was not perfect, I sometimes initially entered numbers in the "wrong" order. No problem. I could easily rearrange a couple of terms and solve the problem without having to enter everything all over again.

Here's to us "pokers."
