Exercise 57 Page 71

Starting at 3, move 8 units in the negative direction.

- 5

Practice makes perfect

We can use a number line to determine the sum 3 +(-8). Starting at 3 on a number line, we will move 8 units to the left. This is eight units in the negative direction. The point at which we stop on the number line illustrates the sum of 3 and -8.

Thus, 3+(-8)=- 5.
