Is RPN still relevant?

[Thomas Radtke]

I tought math and physics for half a year in school and always had the idea that learning algebraic precendece would profit from RPN since this entry system enforces thinking about it. One or two lessons with a concluding competition in getting the correct results from equations I'd write to the blackboard including troubleshooting could be sufficient to get this into the young minds. Not (only) about how to use RPN, but mainly to gain new insights in how to read and look at equations in general.

But of course, there were no affordable RPN calculators available, I was new to the job with no time for experiments, and then there was C, the students and teachers hell.
