Would you please elaborate on "it's just easier"?
I'm asking from a point of genuine curiosity. I've heard many say that
RPN is easier, or that it takes fewer keys, or otherwise superior to
infix notation. But many of the conversations end up somewhat devolving
into religious like comments about preferences, despite starting with
honest open-minded intentions. (I hope this one doesn't similarly devolve.)
I've heard that there are fewer keys to press for RPN, but the example
equations presented have been effectively he same.
I've heard that RPN is mentally easier. But I apparently don't know
enough RPN to be able to think in RPN natively to evaluate myself.
I dabble with RPN, including keeping my main calculator app on my smart
