## Arithmetic Subtraction

`-`

symbol is used for arithmetic subtraction operator.

arithmetic subtraction operator takes two values/variables as operands and returns the difference of right side operand from the first operand.

```
a - b //variables
6 - 4 //values
```

more than one value/variable can be subtracted from a value in a single expression by chaining subtraction operator.

```
a - b - c - d //variables
6 - 4 - 5 - 10 - 85 //values
```

## Examples

1. subtraction of `b`

from `a`

```
var a = 10;
var b = 25;
var diff = a - b;
console.log(diff);
```

2. subtraction of more than one value/variable from a value

```
var a = 10;
var b = 25;
var c = 14;
var diff = a - b - c;
console.log(diff);
```
