I have been privileged to know some people who did math better than me.
whatever. I use an RPN calculator and do math the proper way.
It's always a pleasure to learn of another fellow RPN fan.
I first obtained an HP RPN calculator in the 70's and have had one ever since. My second significant C program in the 80's was a programmable RPN calculator for UNIX, that I eventually ported to every computer I've used since (Windows, Linux, Mac, etc.). I cannot abide being forced to use algebraic on a computer. Fortunately there exists an app for iOS that emulates a 15C, so my phone and tablet can carry on sane math operations.
