Acronym for Reverse Polish Notation.
The idea of putting your operators after your arguments. Arguments are "pushed" onto a stack, and an operator pop's off the required arguments, computes the result and pushes it back onto the stack. For example:
3 1 2 + *
leaves 6 on the stack. Note that RPM doesn't require any brackets.
