**Prefix notation** is a mathematical notation. It is a way to write down equations and other mathematical formulae. Prefix notation is also known as *Polish notation*. The notation was invented by Jan Ćukasiewicz in 1920. He wanted to simplify writing logic equations.

When prefix notation is used, no grouping elements (like parenthesis) are needed.

With prefix notation, the function is noted before the arguments it operates on.

Some CASIO calculators use prefix notation. Some programming languages that were influenced by lambda calculus, like LISP, use prefix notation.
