Converting Normal Math to RPN

Показать описание
RPN (postfix notation) is super-useful for telling computers how to do order of operations on regular math (infix). Once you understand how to actually evaluate postfix expressions, then it's not too crazy to convert regular expressions into RPN versions.

I use RPN all the time. Haven’t done infix. Very good presentation!!!! Keep it coming!

The second time you solved it you left out the + after the second square root. I made that mistake when I solved it, but saw the error when you did it right the first time.
