PREFIX NOTATION Meaning and
Definition
-
Prefix notation, also known as Polish notation, is a system used in mathematical and logical expressions to represent operations or functions without the need for parentheses. In this notation, the operator or function appears before its operands or arguments.
In prefix notation, each expression begins with the operator followed by its operands. This eliminates any ambiguity that may arise when using traditional infix notation, where the order of operations is determined by parentheses and operator precedence rules.
For example, the expression "2 + 3" is written in prefix notation as "+ 2 3". Similarly, the expression "4 * (6 + 2)" can be written as "* 4 + 6 2" in prefix notation.
Prefix notation offers several advantages. It allows for easy evaluation of expressions, as the order of operations is explicit and unambiguous. It also eliminates the need for parentheses, as each operator is immediately followed by its operands. This makes prefix notation compact and less prone to errors.
Prefix notation is commonly used in computer science, particularly in programming languages and calculators. It is frequently utilized in stack-based algorithms and is well-suited for implementation in machine code. Additionally, it offers a consistent and concise way to represent mathematical expressions, facilitating their manipulation and evaluation.

Etymology of PREFIX NOTATION
The term "prefix notation" comes from the combination of two separate words: "prefix" and "notation".
The word "prefix" originates from the Latin word "praefixus", which means "fixed in front". A prefix is a linguistic element attached to the beginning of a word to modify or alter its meaning.
The word "notation" comes from the Latin word "notare", which means "to mark". Notation refers to a system or method of representing or recording information, typically in a symbolic or written form.
Therefore, in the context of mathematics and computer science, "prefix notation" refers to a system of writing mathematical expressions where operators are placed before their operands, indicating the operations to be performed. It is also known as Polish notation, as it was developed by the Polish mathematician Jan Lukasiewicz in the 1920s.
