Write down an expression in algebraic. Now manually solve it. I'll bet you use RPN and use PMDAS to solve within parentheses calculating the inner parentheses first then combining the sub-expressions to work outward.

Example: Solve

(4+7) * (6+2)
----------------
(3+5) * (9+3)

You'd probably calculate 4+7 and 6+2 then multiply them to get 88. Then you'd calculate 3+5 and 9+3 and multiply them to get 96. Finally, you'd do the division and get 0.9167...

This is the same way you'd solve the expression using an RPN calculator.

Nice point. RPN is quite similar how I compute the fraction. That I never read it exposed in this way.

Indeed I would do:
4+7 (so this in algebraic, but it is small enough to apply RPN too)
6+2

3+5
9+3
