It is best to think of a RPN calculator as a stack machine where data is in the stack and arithmetic operates on the top elements of the stack. The expression 2+3 is written as 2 3 + in RPN. The expression [(9+3) * (4/2)] - [(3x) + (2-y)] is written as 9 3 + 4 2 / * 3 x * 2 y - + - in RPN… ................
