Math worksheet for practicing integer operations: addition, subtraction, multiplication, and division.

Let’s go through each problem one by one. We’re working with integers — positive and negative whole numbers — and doing addition, subtraction, multiplication, and division.

Remember these key rules:

- Adding a negative is like subtracting:
`5 + (-3)` = `5 - 3` = `2`

- Subtracting a negative is like adding:
`5 - (-3)` = `5 + 3` = `8`

- Multiplying or dividing two negatives gives a positive:
`(-4) × (-3)` = `12`
`(-10) ÷ (-2)` = `5`

- Multiplying or dividing a positive and a negative gives a negative:
`6 × (-2)` = `-12`
`8 ÷ (-4)` = `-2`

Now let’s solve each problem carefully.

Left Column:

1. `-9 ÷ 1 = -9`
→ Dividing by 1 doesn’t change the number.

2. `-8 - (-6) = -8 + 6 = -2`
→ Subtracting negative is adding.

3. `-5 - 8 = -13`
→ Both negative direction.

4. `-6 + (-4) = -10`
→ Adding negatives.

5. `-7 - (-4) = -7 + 4 = -3`

6. `14 ÷ (-2) = -7`
→ Positive ÷ negative = negative.

7. `7 + (-3) = 4`

8. `1 × 6 = 6`

9. `9 - 9 = 0`

10. `8 - (-7) = 8 + 7 = 15`

11. `4 × (-9) = -36`

12. `1 × (-9) = -9`

13. `-4 × 2 = -8`

14. `-7 - (-1) = -7 + 1 = -6`

15. `9 + 3 = 12`

16. `1 - 3 = -2`

17. `54 ÷ (-9) = -6`

18. `-1 + 8 = 7`

19. `4 + (-6) = -2`

20. `-20 ÷ (-5) = 4`
→ Negative ÷ negative = positive.

21. `49 ÷ (-7) = -7`

22. `2 + 8 = 10`

23. `-8 + (-2) = -10`

24. `-2 × 7 = -14`

25. `-8 × 1 = -8`

Right Column:

1. `1 × (-7) = -7`

2. `-72 ÷ (-9) = 8`
→ Negative ÷ negative = positive.

3. `-4 + 7 = 3`

4. `2 + (-1) = 1`

5. `-48 ÷ (-8) = 6`

6. `1 - 1 = 0`

7. `6 + (-2) = 4`

8. `1 × (-4) = -4`

9. `7 - 8 = -1`

10. `-5 + 9 = 4`

11. `5 + 7 = 12`

12. `-42 ÷ (-6) = 7`

13. `9 × (-4) = -36`

14. `4 × (-3) = -12`

15. `-4 + (-8) = -12`

16. `-3 - (-2) = -3 + 2 = -1`

17. `-9 + 8 = -1`

18. `-6 - 7 = -13`

19. `5 × (-3) = -15`

20. `6 - 6 = 0`

21. `2 ÷ 2 = 1`

22. `-3 + (-3) = -6`

23. `-2 × 2 = -4`

24. `-3 - 1 = -4`

25. `8 × (-8) = -64`
