# PHP Arithmetic Operators

## Arithmetic operators in PHP

PHP supports all standard arithmetic operations, as illustrated by the list of Operators .

Common Arithmetic Operators
Operatos Description
- Subtract
* Multiply
/ Divide and return quotient
% Divide and return modulus

### Here's example illustrating these operators in action

PHP Arithmetic operators are used to perform mathematical operation on more than one operands.

Some of the standard arithmetic operators are +,-,*,/,%.

The use of some common arithmetic operators is here illustrated by an example as follows:-

### Arithmetic operators (+) for addition

```<?php

\$x=10;

\$y=5;

\$sum=\$x+\$y;

echo "sum=".\$sum."<br/>";

?>

```
Output sum = 15

### Arithmetic operators (-) for subtraction

```<?php

\$x=10;

\$y=5;

//subtraction
\$sub=\$x-\$y;

echo "sub=".\$sub."<br/>";

?>

```
Output sub = 5

### Arithmetic operators (*) for multiplication

```<?php

\$x=10;

\$y=5;

//Multiply
\$multiply=\$x*\$y;

echo "Multiplication = ".\$multiply."<br/>";

?>

```
Output Multiplication = 50

### Arithmetic operators (/) for quotient

```<?php

\$x=10;

\$y=5;

//quotient
\$div=\$x/\$y;

echo "Div = ".\$div."<br/>";

?>

```
Output Div = 2

### Arithmetic operators (%) for remainder

```<?php

\$x=10;

\$y=3;

//remainder
\$rem=\$x%\$y;

echo "remainder=".\$rem."<br/>";

?>

```
Output sub = 0

\$x and \$y are two integer variables here there are five blocks/modules in this example they are to preform addition, subtraction, multiplication, division and modulus respectively.

\$x store the value 10, \$y store the value 5. The output of first module is addition of two values 10 and 5 that is 15 (\$x+\$y=15).

The output of second module is subtraction of two values 10 and 5 that is 5 (\$x-\$y=5).

The output of third module is multiplication of two values 10 and 5 that is 50 (\$x*\$y=50).

The output of fourth module is division of two values 10 and 5 that is 2 (\$x/\$y=2).

The output of last module is modulus of two values 10 and 3 that is 1 (\$x%\$y=1).
