Exercise 8 Page 448

Instead of adding a negative number, you can subtract.

- 14

Let's perform the addition.

- 8+(- 6)
- 8 - 6
- 14
We can see that adding a negative number is the same as subtracting its positive counterpart. Below we will demonstrate this addition by finding - 8 and moving 6 units to the left on the number line.

The resulting position, after moving to the left on the number line, is the sum. -8+(- 6)= - 14
