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:**

`900`

## 2. - (Subtraction)

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:**

`100`

## 3. * (Multiplication)

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:**

`20`

## 4. / (Division)

The / operator divides the assigned operand/value.

```
let num1 = 20;
let num2 = 5;
let div = num1 / num2;
console.log(div)
```

**Output:**

`4`

## 5. % (Modulus)

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

```
let num1 = 10;
let mod = num1 % 3;
console.log(mod)
```

**Output:**

`2`

## 6. ++ (Increment)

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:**

`20001`

## 7. -- (Decrement)

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:**

`19999`
