Description: Arithmetic operators in programming are symbols used to perform basic mathematical operations such as addition, subtraction, multiplication, and division. These operators are fundamental as they allow for the manipulation of numeric data and efficient calculations. In PHP, arithmetic operators include the plus sign (+) for addition, the minus sign (-) for subtraction, the asterisk (*) for multiplication, the slash (/) for division, and the percentage sign (%) for the modulus, which returns the remainder of a division. Additionally, PHP allows the use of increment (++) and decrement (–) operators to increase or decrease a variable’s value by one. The correct use of these operators is essential for developing applications that require mathematical calculations, from simple scripts to complex web applications. Their simplicity and effectiveness make them an integral part of the language, enabling developers to implement mathematical logic in their programs.
