JavaScript Arithmetic Operators

The JavaScript Arithmetic Operators includes operators like Addition, Subtraction, Multiplication, Division and Modulus. All these operators are binary operators which means they operate on two operands.

Below table shows the Arithmetic Operators in JavaScript with examples.

JavaScript Arithmetic Operators	Operation	Example
+	Addition	10 + 2 = 12
–	Subtraction	10 – 2 = 8
*	Multiplication	10 * 2 = 20
/	Division	10 / 2 = 5
%	Modulus – It returns the remainder after the division	10 % 2 = 0 (Here remainder is zero). If it is 10 % 3 then it will be 1.

JavaScript Arithmetic Operators Example

For this example, We are using two variables a and b and their values are 12 and 3. We are going to use these two variables to perform various arithmetic operations in JavaScript Programming Language

JAVASCRIPT CODE

<!DOCTYPE html>
<html>
<head>
    <title>Javascript Arithmetic Operators</title>
</head>
<body>
    <h1>Performing Arithmetic Operations </h1>
<script>
   var a = 12, b = 3;
   var addition, subtraction, multiplication, division, modulus;

   addition = a + b; //addition of 3 and 12
   subtraction = a - b; //subtract 3 from 12
   multiplication = a * b; //Multiplying both
   division = a / b; //dividing 12 by 3 (number of times)
   modulus = a % b; //calculation the remainder

   document.write("Addition of " + a +' and ' + b +" is = " + addition + "<br />");
   document.write("Subtraction of " + a +' and ' + b +" is = " + subtraction + "<br />");
   document.write("Multiplication of " + a +' and ' + b +" is = " + multiplication + "<br />");
   document.write("Division of " + a +' and ' + b +" is = " + division + "<br />");
   document.write("Modulus of " + a +' and ' + b +" is = " + modulus + "<br />");
</script>

JavaScript Arithmetic Operators Example 2

For this example also, We are using two variables a and b and their values are 12 and 3.

Here. we are going to use these variables to show you, How to display the JavaScript output in Paragraphs.
