10.4: Be aware of a Calculator widget bug
Authored by: colter on May 24, '05 12:18:24PM

It's not necessarily unintuitive, it's just different from what we're taught in school. I learned RPN when I got an HP 48-GX for college, and I've never looked back. The appeal of RPN entry is that it's simpler and, as you said, not ambiguous. You first provide the data you're working with and then specify what you want done with that data. It comes down to personal preference; I think it's easier to work in RPN.

You're doing the same thing, whether it's written as infix or postfix notation. One way, you learn to resolve operations in PEMDAS order. The RPN way, you learn to do it as you go.
