$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

|
$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
|
