At the end those could be summarized by "Engineers compose the formula on the fly while typing, especially on the field, so RPN is more versatile for the job". I actually like both! Algebraic is the way I'd write the expression but RPN is the way I'd manually solve the expression. 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 subexpressions 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. Tom L Cui bono?
