I was explaining RPN to a friend. He was somewhat unconvinced and said: -I would like to have a system that works like I do it on paper. That's how my calculator works. -OK, I said, -let's look at how you do it on paper. You write down the first number, right? -Right. -Then you write the second number, right? -Right. -Then you apply the operation, right? -Right. -And then you have the answer, right? -Right. -That's also exactly how RPN works, don't you see? He thought about it for a moment. -You are right! Now I'm convinced.
