Stands for Reverse Polish Notation, because it was invented by a Polish mathematician named Lukasiewicz. RPN is a way of expressing a series of mathematical operations, commonly founded on Hewlett-Packard calculators.
RPN is characterized by placing an operator after the quantities on which it operates. For example, this expression
a + ( b / ( c + d ) ) - ewould be expressed this way in RPN:
a b c d + / + e -
