Using The Number Line
We can use the Number Line to help us add:
![]() |
5 + 3 = 8 |
And subtract:
![]() |
6 − 5 = 1 |
It is also great to help us with negative numbers:
![]() |
![]() |
−3 + 2 = −1 |
−3 − 2 = −5 |
So when we get puzzling questions like "What is −6 plus 3" we can use the number line!
