WebThe Three Notations. Infix: When we say 9+10, that is infix notation - that is, the operator is in between the operands. It's the one we're all familiar with. Prefix: also known as Polish notation - is where the operator sits before the operands. Postfix: also known as Reverse Polish Notation or RPN- is where the operator sits after the operands.
