2. (-17) + (+13) + (-3) + (-4)

-17 + 13 = -4

-4 - 3 + (-4)

-4 - 3 = -7

-7 + (-4) = -7 - 4 = -11

3. (+4) + (+10) + (-5)

4 + 10 = 14

14 + (-5) = 14 - 5 = 9

4. (+15) + (+13) + (-10) + (-8) + (-1)

15 + 13 = 28

28 + (-10) + (-8) + (-1)

28 - 10 = 18

18 - 8 - 1 = 9

6. (-3) + (-22) + (+6) + (+10)

(-3) - 22 = -25

-25 + (+6) + (+10)

-25 + (+6) = -19

-19 + (+10) = -9

7. (+6) + (-5) + (+3) + (-9)

6 - 5 = 1

1 + (+3) + (-9) = 4 + (-9)

8. (+14) + (-3) + (-15) + (-9)

14 - 3 = 11

11 - 15 + (-9) = -4 + (-9)
