Section 1.5
Adding Integers

2. Another word for opposite number is the additive inverse
When you add a number and its opposite, you get zero

3. Think of some real life examples where something goes forward and backward or up and down.

4. Integers are either positive, negative or zero.
Think of all the negative numbers on one team
Think of all the positive numbers on another team
Zeroes are not on any team

5. If the positives are a bigger number, they win.
If the negatives are a bigger number, they win
If the positives and negatives are the same, you get zero

6. When adding integers, decide if the positives or negatives are bigger
When adding integers, decide if the positives or negatives are bigger. Write down + or -
Then decide how much bigger.
