What Polish Notation Converter does

The Polish Notation Converter on Omni Calculator transforms arithmetic expressions between different notational formats. Users can convert standard infix notation (symbols between numbers) into prefix (Polish) or postfix (Reverse Polish) notation, and vice versa. The tool maintains mathematical integrity, ensuring converted expressions evaluate to the same values as the originals. It supports basic arithmetic operators (+, -, *, /) and exponentiation (^), as well as variable placeholders using letters instead of numbers. Beyond simple conversion, the page educates users on the history and logic of mathematical notation, explaining why different formats exist and how they affect calculation order. This makes it useful not just for quick conversions, but for learning the fundamentals of arithmetic representation.
