In this tutorial, you shall learn about Arithmetic Operators in PHP, different Arithmetic Operators available in PHP, their symbols, and how to use them in PHP programs, with examples.
Arithmetic Operators
Arithmetic Operators are used to perform basic mathematical arithmetic operators like addition, subtraction, multiplication, etc.
Arithmetic Operators Table
The following table lists out all the arithmetic operators in PHP programming.
| Operator | Symbol | Example | Description |
|---|---|---|---|
| Addition | + | x + y | Returns addition of x and y. |
| Subtraction | – | x - y | Returns the subtraction of y from x. |
| Multiplication | * | x * y | Returns the multiplication of x and y. |
| Division | / | x / y | Returns the quotient of the result of division of x by y. |
| Modulus | % | x % y | Returns the reminder of division of x by y. Known as modular division. |
| Exponent | ** | x ** y | Returns x raised to the power y. |
Example
In the following program, we will take values in variables $x and $y, and perform arithmetic operations on these values using PHP Arithmetic Operators.

<?php
$x = 5;
$y = 2;
$addition = $x + $y;
$subtraction = $x - $y;
$multiplication = $x * $y;
$division = $x / $y;
$modulus = $x % $y;
$exponentiation = $x ** $y;
echo "x = $x" . "<br>";
echo "y = $y" . "<br>";
echo "x + y = $addition" . "<br>";
echo "x - y = $subtraction" . "<br>";
echo "x * y = $multiplication" . "<br>";
echo "x / y = $division" . "<br>";
echo "x % y = $modulus" . "<br>";
echo "x ** y = $exponentiation";
