Round 3 of 4 - Algebraic vs RPN - TVM

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.

You can also save a keystroke if you tye 5000 as 5 EEX 3

5 [×10^x] 3 on fx-991EX or ES plus. 4 for 50,000 5 for 500,000

Also 20 keystrokes on the 48GX ;-) .04 ENTER 12 / 1 + 12 ENTER 5 * Y^x 5000 * = 20 keystrokes. Fair is fair

Thanks to Paco Anton remark: 19 keystrokes on HP-15C: [ . ] 0 4 [ENTER] 1 2 [ / ] 1 [ + ] 1 2 [ENTER] 5 [ * ] [y^x] 5 [EEX] 3 [ * ]

I like to save keystrokes on the Prime by using the touchscreen instead of clicking twice or more if it's beneficial to do so.

[@KrazyCouch2]

I'm aware it's not very orthodox.

@@KrazyCouch2 I think you make a good point -- why not use the touchscreen if it is more efficient?
