As an adult I've discovered the joys of RPN for calculators. I use free42/plus42 on my phone which is an opensource simulator of the HP42. My kids havent started using calculators yet, but I'm debating whether it's a good idea to teach them RPN. I think it's a better way of using calculators, but don't want them to get confused in class. Add to that there isn't a simple RPN calculator that I know of.
- albrewer 4y agoAs a newly-graduated mechanical engineer with 8 years of being on the TI-8(1|2|3) bandwagon, I bought a HP-35s six months after graduating because my co-worker would consistently get answers faster than me on his calculator. It's just faster to key in everyday things in RPN vs infix notation.
- dm319 4y agoAgree - I like being able to just start putting the values in before I've figured out what needs calculated first. You can then shuffle them around and bring in value from further up the stack as they're needed, all while seeing intermediate results. That beats having to backtrack to add brackets, or saving to memory registers because your calculated value is the denominator or something. One day I'll buy a macro/numpad with an LCD screen and run some kind of simple RPN for my desk.
