Does anyone use a RPN calculator ?

Is RPN worth learning ?

This was my first calculator as a kid, not my photo, though I think it is somewhere in my Dads loft. I was the first kid in my school to get a calculator, must have been about 1977.

That switch is odd that it goes from right to left to turn it on?

Luckily they remembered to write on and off in the corresponding positions so you wouldn't be confused.

Three. The oldest is this:

It's still in use at home. The date is hard to read - it's the first part of the "Date of Supply", and it's "17 XII 77". The only thing wrong with it is that the battery cover won't stay closed. I also have a scientific calculator (Casio fx-85W) which I don't use (explained later) plus a basic four-function at work.

For a start, I learned many years ago that "the right tool for the job" is important. There's a tendency these days for people to select easiest tool, or the one that is to hand, but best is best. Yes, your phone has a calculator, but try using it quickly and you'll see how slow it is. That's why I don't use the scientific calculator I have: it's actually quite slow and non-intuitive. And the work machine is so that if I spill something unpleasant on it, so what.

Which way around would be correct if it was vertical?
