<P> Reverse Polish notation ( RPN ) , also known as Polish postfix notation or simply postfix notation , is a mathematical notation in which operators follow their operands , in contrast to Polish notation ( PN ) , in which operators precede their operands . It does not need any parentheses as long as each operator has a fixed number of operands . The description `` Polish '' refers to the nationality of logician Jan Łukasiewicz , who invented Polish notation in 1924 . </P>
