Introduction
This appendix describes the RPN operating mode, and how to work with
this mode. It also describes how to use the interactive stack commands to
manipulate the objects on the stack.
RPN stands for Reverse Polish Notation. The main feature of this notation
is that you specify operations after the numbers or objects to operate on.
Wlien you use the HP 49G in RPN mode, you have access to the stack.
RPN mode, in conjunction with the stack, makes it easy to re-use the
results of previous operations, and to perform chains of calculations.
