Reverse Polish Notation

Reverse Polish Notation (RPN) is a mathematical notation where operators follow their operands, eliminating the need for parentheses to indicate operation order. It is used in stack-based evaluation and is the basis for some calculators and programming languages. This postfix notation simplifies parsing and computation in computer systems.

Also known as: RPN, Postfix Notation, Postfix, Suffix Notation, Reverse Polish
🧊Why learn Reverse Polish Notation?

Developers should learn RPN for implementing stack-based algorithms, compilers, and interpreters, as it simplifies expression evaluation and reduces parsing complexity. It is particularly useful in calculator applications, Forth-like languages, and low-level programming where efficient computation is critical.
