As I wrote. If I cannot see the formula I am typing, I don't find the RPN bad. (and even if I can type, you are right, fractional formulas are not that easy too type too)

Anyway I would first do the numerator, then ANS / (denominator) .
In algebraic.

In RPN would be quite similar.
7 12 + 5 23 + *
3 18 + 4 12 + *
/

My point is though, aside from some edge cases, it is easier to follow the written form. In RPN I have to rework it in my mind.
First I extrapolate what I need first, then I proceed with the rest. This is surely a pedagogical advantage, but after a while it is just overhead for my point of view.
Why is it overhead? Because I do not write the formula in RPN. I am not geared towards it when I manipulate the formula on paper. You yourself wrote in algebric form to communicate with me and the rest of the forum, not in RPN directly.
