Exercise 22 Page 34

Instead of adding a negative number, you can subtract.

- 24

Practice makes perfect

Let's perform the addition.

- 14+(-10)

a+(- b)=a-b

- 14-10

Subtract term

- 24

We can see that adding a negative number is the same as subtracting its positive counterpart. Below we will demonstrate by finding - 14 and moving 10 units to the left on the number line.

The resulting position after moving to the left on the number line is the sum. - 14+(-10)=- 24
