Perhaps my mind was young and agile, but I had no trouble adapting to RPN. The only trick is to understand what's in the stack and enter your expression appropriately. That takes an understanding of the calculation being performed, rather than monkey see, monkey do left-to-right-even-if-its-wrong approach.

The early "algebraic" calculators were actually half-RPN. If you needed to calculate sin(x+y), you entered x + y sin.

I like the mentality of RPN where effectively you gather all the components together, and thereafter do something with them. The get half, decide to do something, find the other half, complete it mentality is deeply unsatisfying.

Having said that, I can tolerate some of the algebraic calculators on the market - the ones which implement arithmentic correctly using BEDMAS so that 1+2*3=7.

Truth is, I can use a full algebraic calculator, an RPN or even a basic boring 4 banger if special functions aren't needed.

I just adapt to the tools available at the time.

"Doing more with less" is always satisfying.
