Arithmetic Operators javascript

With numbers various mathematical operation can be performed, Javascript provides different operators to work with numbers. They are as follows

Addition

+ (plus) operator performs addition operation and adds two or more numbers or variables. In String + joins or concatenate two or more strings.

<script>
let a = 60;
let b = 40;

let result = a + b;
document.write(result);
</script>

Subtraction

– (minus) operator subtract two or more numbers or variables.

<script>
let a = 60;
let b = 40;

let result = a - b;
document.write(result);
</script>

Multiplication

* (asterisk) used to multiply two or more numbers.

<script>
let a = 60;
let b = 40;

let result = a * b;
document.write(result);
</script>

Division

/ (Forward slash) used to perform division.

<script>
let a = 60;
let b = 40;

let result = a / b;
document.write(result);
</script>

Remainder

% (Modulus or Percentage) is used to get remainder after dividing numbers.

<script>
let a = 60;
let b = 40;

let result = a % b;
document.write(result);
</script>

Exponentiation

** (Double Asterisk without space called Exponentiation Operator). Gives Exponent of First number raises the power of second number,

<script>
let a = 60;
let b = 40;

let result = a ** b;
document.write(result);
</script>

Increment

++ is increment operator, increases value by 1. It can be used as post or pre increment operator.

<script>
let a = 60;

// Post Increment
let result = a++;
document.write(result);

// Pre Increment
result = ++a;
document.write(result);
</script>

Decrement

— is Decrement operator, decreases value by 1. It can be used as post or pre Decrement operator.

<script>
let a = 60;

// Pre Decrement
let result = a--;
document.write(result);

// Pre Decrement
result = --a;
document.write(result);
</script>
