Overview

JavaScript arithmetic operators are essential tools that allow you to perform basic mathematical operations in your code. Whether you’re adding numbers, subtracting, multiplying, dividing, or finding remainders, these operators make it easy to work with numbers in JavaScript. In this post, we’ll break down each operator and provide simple examples so you can get started using them in your own projects.

JavaScript Arithmetic Operators Explained

JavaScript offers several arithmetic operators to help you perform calculations with ease. Here’s a quick overview of each:

Addition (+)

  • The + operator adds two numbers together.

Example:

let sum = 5 + 3; // sum is 8

Subtraction (-)

  • The - operator subtracts one number from another.

Example:

let difference = 10 - 4; // difference is 6

Multiplication (*)

  • The * operator multiplies two numbers.

Example:

let product = 6 * 2; // product is 12

Division (/)

  • The / operator divides one number by another.

Example:

let quotient = 10 / 2; // quotient is 5

Modulus (%)

  • The % operator returns the remainder of a division.

Example:

let remainder = 10 % 3; // remainder is 1

Conclusion

JavaScript arithmetic operators are powerful tools for performing basic math in your code. Whether you’re adding, subtracting, multiplying, dividing, or finding remainders, these operators are simple to use and crucial for any JavaScript developer. Practice using these operators in different scenarios, and soon you'll be comfortable handling numbers in your JavaScript programs!
