Arithmetic Operators in JavaScript

The standard Arithmetic operators are as follows:

OperatorsDescription
Addition+
Subtraction-
Multiplication*
Division/
Modulus%
Increment++
Decrement--

Let see Example of each

Addition

<script type="text/javascript>
 var x = 5;
 var y = 3;
 var result = x + y;
 document.write("Final Result is " + result);
</script>

The answer will be 8 which is 5 + 3

Subtracion

<script type="text/javascript>
 var x = 5;
 var y = 3;
 var result = x - y;
 document.write("Final Result is " + result);
</script>

The answer will be 2 which is 5 – 3

Multiplication

<script type="text/javascript>
 var x = 5;
 var y = 3;
 var result = x * y;
 document.write("Final Result is " + result);
</script>

The answer will be 15 which is 5 * 3

Division

<script type="text/javascript>
 var x = 5;
 var y = 3;
 var result = x / y;
 document.write("Final Result is " + result);
</script>

The answer will be 1.6666666 which is 5 / 3

Modulus

<script type="text/javascript>
 var x = 5;
 var y = 3;
 var result = x % y;
 document.write("Final Result is " + result);
</script>

The answer will be 2 which is 5 % 3. It will show the remainder

Increment

<script type="text/javascript>
 var x = 5;
 var y = 3;
 var result = x + y;
 result++
 document.write("Final Result is " + result);
</script>

The answer will be 9. It will increment 8 by 1

Decrement

<script type="text/javascript>
 var x = 5;
 var y = 3;
 var result = x + y;
 result--
 document.write("Final Result is " + result);
</script>

The answer will be 7. It will decrement 8 by 1
