## PHP : 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.

Example :

1. \$x=100;

2. \$y=60;

3. echo "The sum of x and y is : ". (\$x+\$y) ."
";

4. echo "The difference between x and y is : ". (\$x-\$y) ."
";

5. echo "Multiplication of x and y : ". (\$x*\$y) ."
";

6. echo "Division of x and y : ". (\$x/\$y) ."
";

7. echo "Modulus of x and y : " . (\$x%\$y) ."
";

8. ?>

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.
