JavaScript: Arithmetic Operators

Arithmetic operator, is a type of operator used to do some simple mathematical stuff in the javascript programming language.

An arithmetic operator is comprised of many mathematical functions to do the math stuff.
Arithmetic Operators are ( +, -, *, /, --, %, ++ ) , we will see one by one with a perfect code example to understand what is happening in a code while using arithmetic operators.

1. + (Addition)

The + is an operator that performs the additional math function using the operands/value we assign in a variable.

let num1 = 400;
let num2 = 500;

let sum = num1+num2;

console.log(sum)

Output:

The - is an operator which performs the subtraction math function using some of the operands/values we assign in a variable same as the + function.

let num1 = 400;
let num2 = 500;

let diff = num2 - num1;

console.log(diff)

Output:

The * is an operator which performs the multiplication math function using the operands we assign.

let num1 = 4;
let num2 = 5;

let mul = num1 * num 2;

console.log(mul)

Output:

The / operator divides the assigned operand/value.

let num1 = 20;
let num2 = 5;

let div = num1 / num2;

console.log(div)

Output:

The modulus operator % divides the provided value and gives out the remainder/leftover.

let num1 = 10;

let mod = num1 % 3;

console.log(mod)

Output:

The ++ or increment operator increments/increase the provided value within a variable when initiated after the declaration.

let neoSalary = 20000;

neoSalary++

console.log(neoSalary)

Output:

The -- or decrement operator decrements/decrease the provided value within a variable when initiated after the declaration.

let neoSalary = 20000;

neoSalary--

console.log(neoSalary)

Output:
