Grade 7 Multiply & Divide Integers worksheet
from Gradelings · Name: ______________________
How to explain it
- Same signs give a positive answer: (+)(+) and (−)(−).
- Different signs give a negative answer.
- Division follows the same sign rules as multiplication.
Example: (−6) × (−4) = ? Both signs are negative, so the answer is positive. 6 × 4 = 24. Answer: 24
Question 1
What is the value of (-6 + 7) × (-3)?
(-6 + 7) × (-3)
- -3
- 3
- -2
- -27
-3
Hint: Brackets first: -6 + 7 = 1. Then 1 × (-3) = -3.
Question 2
What is -36 ÷ (-9)?
-36 ÷ (-9) = ?
- -4
- 3
- 4
- 5
4
Hint: Use the fact 9 × 4 = 36. Same signs give a positive answer, so the answer is 4.
Question 3
What number goes in the box?
10 × = -60
answer box
-6
Hint: Divide: -60 ÷ 10 = -6. Check: 10 × (-6) = -60.
Question 4
Use the order of operations (BEDMAS) to evaluate: 8 − 7 × (-3)
8 − 7 × (-3)
answer box
29
Hint: Multiply first: 7 × (-3) = -21. Then 8 − (-21) = 8 + 21 = 29.
Question 5
Without multiplying it out, is this product positive or negative? 7 × 4 × 3 × 8
- Negative
- Positive
Positive
Hint: None of the factors is negative, so the product is positive.
Question 6
What is -3 × (-3)?
-3 × (-3) = ?
answer box
9
Hint: 3 × 3 = 9. Same signs give a positive product, so the answer is 9.
Question 7
What is 7 × 4?
7 × 4 = ?
answer box
28
Hint: Split 7 into 5 + 2: 4 × 5 = 20 and 4 × 2 = 8. Add them: 28.
Question 8
The temperature dropped 9°C every hour for 4 hours. What integer shows the total change in temperature?
answer box°C
-36 °C
Hint: A drop is negative, so multiply: 4 × (-9) = -36.
Question 9
Use the order of operations (BEDMAS) to evaluate: 14 − 6 × 3
14 − 6 × 3
answer box
-4
Hint: Multiply before you subtract: 6 × 3 = 18. Then 14 − 18 = -4.
Question 10
Without multiplying it out, is this product positive or negative? (-9) × (-7) × (-9)
- Negative
- Positive
Negative
Hint: Count the negative factors: there are 3. An even number of negatives gives a positive product; an odd number gives a negative product.
