# Inequalities and integers

## Integer – a number which is not a fraction; a whole number

If you are asked for all the possible answers of `n` in:

`-1<=n<=4`

Where `n` is an integer,

Then this is asking you to write down all the possible whole numbers between `-1` and `4`, including `-1` and `4`.

**Examples**

1. Write down all the possible answers to

`-1<=n<=4`

Where `n` is an integer

**Answer:** `-1, 0, 1, 2, 3` and `4`

2. Write down all the possible answers to

`-1<n<4`

Where `n` is an integer

**Answer:** `0, 1, 2` and `3`

**NOTE:**

We have not included `-1` and `4`

3. Write down all the integers that satisfy:

`-16<\x\<-13`

**Answer:** `-15` and `-14`

4. Write down all the integers that satisfy:

`-13<=\x\<-10`

**Answer:** `-13,-12` and `-11`
