Arithmetic operators are symbols that represent computations like addition, multiplication, and division. JavaScript supports several arithmetic operators, including:

• + (Addition)
• - (Subtraction)
• * (Multiplication)
• / (Division)
• % (Modulus)
• ++ (Increment)
• -- (Decrement)

How to Use Arithmetic Operators

Here’s a brief explanation of how each operator works:

Addition (+)

The + operator adds two numbers together.

let sum = 5 + 3; // sum will be 8

Subtraction (-)

The - operator subtracts one number from another.

let difference = 5 - 3; // difference will be 2

Multiplication (*)

The * operator multiplies two numbers together.

let product = 5 * 3; // product will be 15

Division (/)

The / operator divides one number by another.

let quotient = 6 / 3; // quotient will be 2

Modulus (%)

The % operator returns the remainder of a division operation.

let remainder = 7 % 3; // remainder will be 1

Increment (++)

The ++ operator increases a number by 1.

let num = 5;
num++; // num will be 6

Decrement (--)

The -- operator decreases a number by 1.

let num = 5;
num--; // num will be 4

JavaScript’s arithmetic operators are fundamental to performing mathematical operations in your code. They are essential tools in every developer’s toolkit.
