JavaScript Arithmetic Operators

The JavaScript Arithmetic Operators include operators like Addition, Subtraction, Multiplication, Division, and Modulus. All these operators are binary operators, which means they operate on two operands. The below table shows the Arithmetic Operators in JavaScript with examples.

JS Arithmetic OperatorsOperationExample
+Addition10 + 2 = 12
Subtraction10 – 2 = 8
*Multiplication10 * 2 = 20
/Division10 / 2 = 5
%Modulus – It returns the remainder after the division10 % 2 = 0 (Here remainder is zero). If it is 10 % 3 then it will be 1.

JavaScript Arithmetic Operators Example

For this JavaScript Arithmetic operations 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

Performing Arithmetic Operations
Addition of 12 and 3 is = 15
Subtraction of 12 and 3 is = 9
Multiplication of 12 and 3 is = 36
Division of 12 and 3 is = 4
Modulus of 12 and 3 is = 0

JavaScript Arithmetic Operations Example 2

For this JavaScript 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.
