Definitions from the WebPrefix NotationDefinition: Prefix notation, also known as Polish notation, is a mathematical notation in which operators are placed before their operands. It is a way of writing arithmetic and logical expressions without the need for parentheses to define the order of operations. Sense 1: In computer science and programming, prefix notation is commonly used in programming languages and calculators to evaluate expressions. For example, the addition of numbers 7 and 5 can be written as "+ 7 5" in prefix notation. Sample Sentence: In prefix notation, the expression "- / 15 3 5" is evaluated as "subtract the division of 15 by 3 from 5," resulting in the value of 2. Sense 2: Prefix notation is also used to represent network addresses, IP addresses, and binary numbers in computer networking. Sample Sentence: The network address 192.168.0.0/24 can be represented in prefix notation as 192.168.0.0 with a subnet mask of 255.255.255.0.
