Now that we know how to add and subtract negative numbers, let’s have some practice. Which of the following groups contains a mistake?
8 + ( − 6)
= 2
− 5 − ( − 8)
= 3

3 + ( − 6)
= − 3
− 1 + ( − 7)
= − 8
− 4 − ( − 8)
= + 4
− 3 − ( − 6)
= − 9
⎫ ⎬ ⎭ This group contains a mistake .
2 − ( − 3)
= 5
− 16 + 2
= − 14
1 + ( − 3)
= − 2
− 11 + ( − 1)
= − 12
⎫ ⎬ ⎭ This group contains a mistake .
− 4 + 3
= − 1
− 7 − ( − 3)
= − 4
6 − 8
= − 2
− 9 + ( − 2)
= − 11
