- 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.
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.
there is an odd number of negatives so they answer will be a negative
the same goes for this.
