Arithmetic Operators



Perl Arithmetic Operators:

Assume variable $a holds 10 and variable $b holds 20 then:
Operator
Description
Example
+
Addition - Adds values on either side of the operator
$a + $b will give 30
-
Subtraction - Subtracts right hand operand from left hand operand
$a - $b will give -10
*
Multiplication - Multiplies values on either side of the operator
$a * $b will give 200
/
Division - Divides left hand operand by right hand operand
$b / $a will give 2
%
Modulus - Divides left hand operand by right hand operand and returns remainder
$b % $a will give 0
**
Exponent - Performs exponential (power) calculation on operators
$a**$b will give 10 to the power 20
