But it seems to have worked on early 12CPs, as Robert noted.

I prefer the other way as it can shorten and simplify quite a lot of calculations. For instance the sum formula (n²+n)/2, that's simply + x² / 2. Add an "=" before the division, if required.

On some (many, most, all?) TIs, e.g. the 58/59, there even was a way to re-enter the displayed value during a calculation by means of the CE key, as in

5 x ( CE + 1 ) / 2 =

I really appreciated this as it helped overcome the limitations of AOS (a bit).

But then...

That's what I really love about RPN: it's direct, straightforward and unambiguos. It simply does what you tell it to do and intermediate results can be freely stored on the stack.
