Read each question carefully and answer to the best of your ability. Remember that addition and subtraction are inverse operations!
Complete the subtraction problems below.
1. 75 - 23 =
2. 98 - 45 =
3. 52 - 19 =
4. 81 - 37 =
Use the number line to solve the problem and show the inverse operation.
5. Start at 15. Subtract 7. What is the answer?
6. Write an addition problem that is the inverse operation of 20 - 8 = 12.
Determine if the following statements are true or false.
7. 10 + 5 = 15 is the inverse operation of 15 - 5 = 10.
True
False
8. If you know 12 - 4 = 8, then you also know 8 + 4 = 12.
True
False
9. Which addition problem is the inverse operation of 30 - 10 = 20?
10 + 30 = 40
20 + 10 = 30
30 - 20 = 10
10 + 20 = 40
Match each subtraction problem with its inverse addition problem.
10. 45 - 20 = 25
a. 15 + 10 = 25
11. 30 - 15 = 15
b. 25 + 20 = 45
12. 60 - 30 = 30
c. 30 + 30 = 60
