Maybe I'm being clueless/over-asking, but to me it's appalling that any
college student (at least all who have _any_ math requirement at all; not sure
how many that is) doesn't know how an RPN calculator works. It's not exactly
rocket science, and any reasonably intelligent high-schooler should get it
extremely quickly; just tell them it's just a representational thing, number
number operator instead of number operator number. I know it's not a key
intellectual skill, but it does seem to me to be part of comon intellectual
heritage that everyone should know, like musical scales or poetry
rhyming. Have you ever considered taking two minutes (literally!) to cover it
briefly, just 'someone tried to borrow my RPN calculator, here's the basic
idea of how they work'?
