Exercise 1 Page 33

Starting at - 5, move 2 units in the positive direction.

- 3

Practice makes perfect
We can use a number line to determine the sum - 5+2. Starting at - 5 on a number line, we will move 2 units to the right. This is two units in the positive direction. The point at which we stop on the number line illustrates the sum of - 5 and 2.

Thus, - 5+2=- 3.
