Arithmetic Operators
Description

There are five basic arithmetic operators.

- (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) ."<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 case of division, the operator returns a float value if the two operands are not integers.
