how do I do this equation

I now remember when I last used reverse polish, it was on a Sinclair Spectrum, using the operating system to do a calculation in assembly. Everything had to be stacked in RPN before calling the expression evaluator.

That's got to be 25 years ago!!

That's why I like my old HP15C (which stays at work). RPN, no parentheses or brackets required.
The calculator I use here at home when sitting at my computer is an **broken link removed**.

One don't just like RPN, one is addicted to it. I HAVE to use a RPN even I have several other non RPN types.

I feel very uncomfortable if I am forced to use a non-RPN type and have to write down the immediate results I already worked out. No such worry with a RPN.
 

Not very good for PIC's then! - RPN relies on a decent size stack - but if you like RPN you'll probably enjoy using Forth.
 

I never use the exponents key because it never looks quite right to me.
