In no way intended to be an end-all-be-all to the ongoing discussion -- this series of videos simply explores how efficiently an expression can be entered in Algebraic (in-fix) vs RPN (post-fix) calculators.
I attempted to be efficient, and in some cases explored various ways to enter the expression (particularly on the Algebraic calculators) ahead of time. However, the goal was NOT to determine the absolute fewest number of keystrokes possible -- instead, it was to attempt to use each calculator in a manner consistent with the way someone familiar with the device might use it.
