At the computer my level of math escalation is the generic Mac desktop calculator.
From there I may shift to a handy emacs scratch buffer.
After that it moves to firing up Slime into CL. The * * and ** variables (which in CL equate to the 3 most recent evaluation results) is actually quite handy. Plus I just have the Slime history and all that.
None of those are RPN, but at this level I tend to not enter long equations anyway, and I have to do just as much precedence parsing cognitively converting algebraic to RPN or prefix anyway.
