Lesson 1: Adding and Subtracting Integers
When adding and subtracting integers, think of teams.
Blue is going to represent the positive team
Red is going to represent the negative team
MFM1P
Lesson 1: Adding and Subtracting Integers
-5 + 8Negative team has 5
Positive team has 8
The positive team won by 3. So, then answer is +3.
