__Chapter 1: Grade 7 Integer Review__

- To solve integers problems you can use number lines or integer chips
- Usually red chips represent positive numbers and blue chips represent negative numbers
- A zero pair is one negative and one positive together

Here are some examples or subtracting and addition questions on integers:

__Chapter 2: Multiplying Integers__

- When multiplying integers always remember "The Sign Rule" .

The rule is that if there is an odd numbers of negatives in the question, the answer will be a negative number.If there is an even numbers of negatives in the question, the product will be a positive. If there is only positives the answer will always be a positive. - You can also use number lines to show your answer.
- Use the following examples to help you:

__Chapter 3: Dividing Integers__

- Partitive Division is when you know the total number of groups, and you are trying to find the number of items in each group.
- Quotitive Division is when you know the total items that are in each group and you're trying to find the number of groups & sharing you total with groups.

QUOTITIVE DIVISION

The sign rule of addition, subtraction and multiplication also applies to division. For example:

- 6÷2= 3

there are no negative signs therefore the answer will be a positive. - (-6)÷(-2)= +3

there is an even number of negatives meaning the answer will be a positive. - (-6)÷2=-3

there is an odd number of negatives so they answer will be a negative - 6÷(-2)=-3

the same goes for this.
