*Negative Numbers*

- When
**counting down**, after**zero**, you move into**negative numbers**. Remember that the rule of which number is bigger is the opposite way around in negative numbers ( for example, -1 is bigger than -2)

- When you have to count between
**negative**and**positive numbers**, the easiest thing to do it draw a number line then**count upwards**from the**negative number**to**zero**, then from**zero**to the**positive number**and add together to find the difference.

**Example 1:**

Let’s say we need to find the difference between **-34** and **51**. We can draw this on our number line.

The difference between **-34** and **0** is **34** and the difference between **0** and **51** is **51**. If we add these together, we get a **total of** **85**. Therefore, the difference between **-34** and **51 **is **85**.
