I still have my old HP 11c RPN calculator, and I just love how RPN works. I feel like it keeps my brain more focused on the math, rather than worrying about math punctuation! With regular calculators, it is so tedious to type in parentheses and equal signs -- one typo and it's wrong and you spend more time editing a parenthesis than thinking about math!
I just was wondering if it's ever taught at all, or if anyone uses it.
