Adding and Subtracting Integers interactive exercise - Free Printable

Let's solve each of the integer operations step by step, following the rules for adding, subtracting, multiplying, and dividing integers. Remember:

- Addition/Subtraction:
- Same signs: Add absolute values, keep the sign.
- Different signs: Subtract smaller absolute value from larger, take the sign of the larger.
- Multiplication/Division:
- Same signs: Result is positive.
- Different signs: Result is negative.

Column 1

1. 8 + 10 =
$ 8 + 10 = 18 $

2. 7 + (-8) =
$ 7 - 8 = -1 $

3. 7 + 6 =
$ 7 + 6 = 13 $

4. (-3) + 11 =
$ 11 - 3 = 8 $

5. (-8) x 4 =
Negative × Positive = Negative → $ -32 $

6. 3 + (-11) =
$ 3 - 11 = -8 $

7. (-8) x (-4) =
Negative × Negative = Positive → $ 32 $

8. 35 ÷ 5 =
$ 35 ÷ 5 = 7 $

9. (-7) - 7 =
$ -7 - 7 = -14 $

10. 2 x 8 =
$ 2 × 8 = 16 $

Column 2

1. 10 + 9 =
$ 10 + 9 = 19 $

2. 16 ÷ (-4) =
Positive ÷ Negative = Negative → $ -4 $

3. 8 x (-10) =
Positive × Negative = Negative → $ -80 $

4. (-2) + 5 =
$ 5 - 2 = 3 $

5. (-9) x 6 =
Negative × Positive = Negative → $ -54 $

6. 1 x (-7) =
$ -7 $

7. (-7) x (-3) =
Negative × Negative = Positive → $ 21 $

8. 7 - 6 =
$ 7 - 6 = 1 $

9. 9 - 8 =
$ 9 - 8 = 1 $

10. 4 - 10 =
$ 4 - 10 = -6 $

Column 3

1. 2 - 5 =
$ 2 - 5 = -3 $

2. 9 - (-11) =
Subtracting a negative = adding → $ 9 + 11 = 20 $

3. 4 - (-6) =
$ 4 + 6 = 10 $

4. 20 ÷ (-2) =
Positive ÷ Negative = Negative → $ -10 $

5. (-1) x (-10) =
Negative × Negative = Positive → $ 10 $

6. 1 - (-9) =
$ 1 + 9 = 10 $

7. 8 + (-2) =
$ 8 - 2 = 6 $

8. 5 - (-3) =
$ 5 + 3 = 8 $

9. 3 - (-6) =
$ 3 + 6 = 9 $

10. (-11) + 4 =
$ -11 + 4 = -7 $
