A **negative number** is a number **smaller than zero. **This can be clearly seen on the number line below.

One of the activities you will be asked to do is arrange integers in **ascending **order (smallest first).

**Example:**

**-9 0 6 22 -24 -1**

Look at the negative numbers first.

The smallest negative number is **-24,** then **-9**, then **- 1.**

Then look at the positive numbers.

The smallest positive number is** 0,** then **6,** and finally, the largest number is **22.**

The numbers in ascending order are:

**-24 -9 -1 0 6 22**

You will also be asked to calculate with negative numbers mentally.

**Example:**

The temperature on Monday morning is **-4°C.** The temperature on Friday morning is **1°C.** How much warmer is it on Friday morning?

You may be able to do this type of calculation in your head or it may help you to use a number line.

**Answer:** **5°C**
