# PHP: Arithmetic Operators

## Description

There are five basic arithmetic operators.

- + (addition)
- - (subtraction)
- * (multiplication)
- / (division)
- % (modulus)

The operators are summarized in the following table.

Operator | Name | Example | Result |
---|---|---|---|

+ | Addition | $x + $y | Sum of $x and $y. |

- | Subtraction | $x - $y | Difference of $x and $y. |

* | Multiplication | $x * $y | Product of $x and $y. |

/ | Division | $x / $y | Quotient of $x and $y |

% | Modulus | $x % $y | Remainder of $x divided by $y. |

**Example:**

```
<?php
$x=100;
$y=60;
echo "The sum of x and y is : ". ($x+$y) ."<br />";
echo "The difference between x and y is : ". ($x-$y) ."<br />";
echo "Multiplication of x and y : ". ($x*$y) ."<br />";
echo "Division of x and y : ". ($x/$y) ."<br />";
echo "Modulus of x and y : " . ($x%$y) ."<br />";
?>
```

Output:

The sum of x and y is : 160 The difference between x and y is : 40 Multiplication of x and y : 6000 Division of x and y : 1.6666666666667 Modulus of x and y : 40

Note : In the case of division, the operator returns a float value if the two operands are not integers.
