JavaScript Arithmetic Operators

Last Updated:

JavaScript Arithmetic Operators

The arithmetic operators perform arithmetic operations on numbers (either literals or variables) as their operands and return a single numerical value. The following are the list of arithmetic operators available in JavaScript.

Addition

In the following example, we will add the two given numbers (50, 45).

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num1 = 50; var num2 = 45; var result = num1 + num2; document.write(result); </script> </body> </html>

JavaScript Arithmetic Operators

The following are the list of arithmetic operators available in JavaScript.

OperatorExplanationOperationResult
+ Addition 50 + 45 90
- Subtraction 50 - 45 5
* Multiplication 5 * 2 10
/ Division 7 / 2 3
** Exponentiation 5 ** 2 25
% Remainder
(Modulus)
7 % 2 1
++ Increment ++5 6
-- Decrement --5 4

Subtraction

In the following example, we will subtract the two numbers (50 and 45).

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num1 = 50; var num2 = 45; var result = num1 - num2; document.write(result); </script> </body> </html>

Multiplication

In the following example, we will multiply the two given numbers (5 and 2).

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num1 = 5; var num2 = 2; var result = num1 * num2; document.write(result); </script> </body> </html>

Exponentiation

In the following example, we will perform the operation of raising one quantity to the power of another (52).

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num = 5; var result = num ** 2; document.write(result); </script> </body> </html>

Division

In the following example, we will divide the two given numbers (7 by 2).

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num = 7; var result = num / 2; document.write(result); </script> </body> </html>

Modulus

In the following example, we will find the remainder of the two given number (7 and 2) when dividied.

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num = 7; var result = num % 2; document.write(result); </script> </body> </html>

Increment

In the following example, we will increment the given number (3).

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num = 3; var result = ++num; document.write(result); </script> </body> </html>

Decrement

In the following example, we will decrement the given number (3).

Example

HTML Online Editor
<!DOCTYPE html> <html> <body> <script> var num = 3; var result = --num; document.write(result); </script> </body> </html>
