Just out of curiosity, how would you calculate 3.7 + 3.7^2 in RPN? I'd press 3 . 7 ENTER x^2 followed by + .

this gets "too fue arguments" error

I'd do:
3.7 ENTER ENTER * +
(shortest finger travel)


On the OP issue : regardless of the poor wording, one quickly figures out the ENTER behavior;
I've seen (lots of) not-needed ENTERs only in novice's programs.

this gets "too fue arguments" error also
now back to our normally scheduled argument...

Pressing [enter] is optional after entering a number, if the next key
pressed is an operation.

NOTE: pressing [Input] or [=] is optional after keying in a number, if the next key
pressed is an operation.
