In this article, you will learn JavaScript arithmetic operators with the help of examples. In the previous tutorial, we have seen all about **JavaScript operators** and their types.

Before start this article, let’s know little bit about operator.

## What is operator ?

Operator is special type of symbol that is used to perform calculate on values and variables.

## JavaScript Arithmetic Operators

** JavaScript arithmetic operators **are used to perform arithmetic operations. There are various types of operation available in arithmetic operators.

**JavaScript Arithmetic Operators**

Operator | Name | Example |
---|---|---|

+ | Addition | x + y |

– | Subtraction | x – y |

* | Multiplication | x * y |

/ | Division | x / y |

% | Remainder | x % y |

++ | Increment | x ++, ++x |

— | Decrement | x –, –x |

** | Exponentiation | x ** y |

### Arithmetic Operation

Arithmetic operation operates on two numbers and those two numbers can be literals and variables.

### Operators and Operands

The numbers are called operands and operation is defined by operator.

Let’s take simple example to understand operands and operator.

**Example:**

`100 + 20 `

In above table **100** and** 20** are operands, **+** is the operator.

### Addition

The addition operator ( + ) is used to add numbers.

```
var result = 100 + 50;
console.log(result)
```

### Subtraction

The Subtraction operator ( – ) is used to subtract one number from other numbers.

```
var result = 100 - 50;
console.log(result)
```

### Multiplication

The Multiplication operator ( * ) is sued to multiply one or more values.

```
var result = 100 * 50;
console.log(result)
```

### Dividing

The Dividing operator ( / ) is used to divide the numbers.

```
var result = 100 / 50;
console.log(result)
```

### Remainder

The modulus operator ( % ) is used to return the division remainder.

```
var result = 109 / 50;
console.log(result)
```

### Incrementing

Increment operator ( ++ ) is used to increment the numbers.

```
var x = 10;
x++
console.log(x)
```

### Decrement

Decrement operator ( – – ) is used to decrement the numbers.

```
var x = 10;
x--
console.log(x)
```

### Exponentiation

The exponentiation operator (**) raises the first operand to the power of the second operand.

```
var x = 10;
console.log(x ** 2);
```

## Conclusion

In this tutorial, you have learned all about ** JavaScript arithmetic operators** with the help of examples.

Arithmetic operators are always used to perform arithmetic operations on operands. Operands can be values and variables.
