What is Prefix notation?
{{Infobox notation|logo=[[Image:prefix-dia.svg|125px]]}} '''Prefix notation''' is a [[mathematical notation]]. It is a way to write down [[equation]]s and other mathematical [[formula]]e. Prefix notation is also known as ''Polish notation''. The notation was invented by [[Jan Łukasiewicz]] 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]] [[calculator]]s use prefix notation. Some programming languages that were influenced by [[lambda calculus]], like [[LISP]], use prefix notation. {{Math-stub}} <!-- improve this article --> [[Category:Mathematical notation]]
