# Airthmetic operator in JavaScript

The number which is called operands

The operations between two operands are defined by operator

## Arithmetic operators are

the operations between two or more operands perform an Addition operation ( + )

Example :

```<!DOCTYPE html>
<html>
<body>
<script>
var a=18;
var b=20;
document.write(a+b);
</script>
</body>
</html>```

Output: 38

Or

```<!DOCTYPE html>
<html>
<body>
<script>
var a=18;
var b=20;
var c=a+b;
document.write(c);
</script>
</body>
</html>```

Output : 38

### • Subtraction(-)

the operations between two or more operands perform an Subtraction operation ( – ).

Example:

```<!DOCTYPE html>
<html>
<body>
<script>
var a=18;
var b=20;
var c=a-b;
document.write(c);
</script>
</body>
</html>```

Output: -2

### • Multiplication(%)

the operations between two or more operands perform an Multiplication operation ( * ).

Example:

```<!DOCTYPE html>
<html>
<body>
<script>
var a=18;
var b=20;
var c=a*b;
document.write(c);
</script>
</body>
</html>```

Output: 360

### • Division (%)

the operations between two or more operands perform an Division operation ( %).

Example :

```<!DOCTYPE html>
<html>
<body>
<script>
var a=18;
var b=20;
var c=a/b;
document.write(c);
</script>
</body>
</html>```

Example: 0.9

### • Exponential (**)

Exponential it raise the first operand to the power of second operands.

Example:

```<!DOCTYPE html>
<html>
<body>
<script>
var a=2;
var b=3;
var c=a**b;
document.write(c);
</script>
</body>
</html>```

Output: 8

### • Modules (%)

Example:

```<!DOCTYPE html>
<html>
<body>
<script>
var a=20;
var b=3;
var c=a%b;
document.write(c);
</script>
</body>
</html>```

Output : 2

### • Increment (++)

Example:

```<!DOCTYPE html>
<html>
<body>
<script>
var a=20;
document.write(++a);
</script>
</body>
</html>```

Output : 21

### • Decrement(–)

Example:

```<!DOCTYPE html>
<html>
<body>
<script>
var a=20;
document.write(--a);
</script>
</body>
</html>```

Output: 19
