In this article, you will learn JavaScript arithmetic operators with the help of examples. In the previous tutorial, we have seen all about JavaScript operators and their types.
Before start this article, let’s know little bit about operator.

What is operator ?
Operator is special type of symbol that is used to perform calculate on values and variables.
JavaScript Arithmetic Operators
JavaScript arithmetic operators are used to perform arithmetic operations. There are various types of operation available in arithmetic operators.
JavaScript Arithmetic Operators
Operator | Name | Example |
---|---|---|
+ | Addition | x + y |
– | Subtraction | x – y |
* | Multiplication | x * y |
/ | Division | x / y |
% | Remainder | x % y |
++ | Increment | x ++, ++x |
— | Decrement | x –, –x |
** | Exponentiation | x ** y |
Arithmetic Operation
Arithmetic operation operates on two numbers and those two numbers can be literals and variables.
Operators and Operands
The numbers are called operands and operation is defined by operator.
Let’s take simple example to understand operands and operator.
Example:
100 + 20
In above table 100 and 20 are operands, + is the operator.
Addition
The addition operator ( + ) is used to add numbers.
var result = 100 + 50;
console.log(result)
Subtraction
The Subtraction operator ( – ) is used to subtract one number from other numbers.
var result = 100 - 50;
console.log(result)
Multiplication
The Multiplication operator ( * ) is sued to multiply one or more values.
var result = 100 * 50;
console.log(result)
Dividing
The Dividing operator ( / ) is used to divide the numbers.
var result = 100 / 50;
console.log(result)
Remainder
The modulus operator ( % ) is used to return the division remainder.
var result = 109 / 50;
console.log(result)
Incrementing
Increment operator ( ++ ) is used to increment the numbers.
var x = 10;
x++
console.log(x)
Decrement
Decrement operator ( – – ) is used to decrement the numbers.
var x = 10;
x--
console.log(x)
Exponentiation
The exponentiation operator (**) raises the first operand to the power of the second operand.
var x = 10;
console.log(x ** 2);
Conclusion
In this tutorial, you have learned all about JavaScript arithmetic operators with the help of examples.
Arithmetic operators are always used to perform arithmetic operations on operands. Operands can be values and variables.
