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.

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

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
