Exercise 26 Page 34

Instead of adding a negative number, you can subtract.

- 6

Practice makes perfect

Let's perform the addition.

- 2.2+(-3.8)

a+(- b)=a-b

- 2.2-3.8

Subtract term

- 6

We can see that adding a negative number is the same as subtracting its positive counterpart. Below we will demonstrate by finding - 2.2 and moving 3.8 units to the left on the number line.

The resulting position after moving to the left on the number line is the sum. - 2.2+(-3.8)=- 6
