Absolutely! Let’s solve each of the 9 problems step by step. The worksheet says:
“Use the inverse to find the missing numbers.” That means we’ll use subtraction to solve addition problems, and addition to solve subtraction problems — because addition and subtraction are inverse operations.

🧮 Problem 1:
4□ + 15 = 56
We need to find the missing digit in the tens place of the first number.
- Inverse: Subtract 15 from 56 → `56 - 15 = 41`
- So the first number is
41
- Missing digit:
1
✔ Answer:
1

🧮 Problem 2:
□5 - 43 = 52
Find the missing digit in the tens place of the top number.
- Inverse: Add 43 to 52 → `52 + 43 = 95`
- So the top number is
95
- Missing digit:
9
✔ Answer:
9

🧮 Problem 3:
25 + 1□ = 39
Find the missing digit in the ones place of the second number.
- Inverse: Subtract 25 from 39 → `39 - 25 = 14`
- So the second number is
14
- Missing digit:
4
✔ Answer:
4

🧮 Problem 4:
22 + □5 = 57
Find the missing digit in the tens place of the second number.
- Inverse: Subtract 22 from 57 → `57 - 22 = 35`
- So the second number is
35
- Missing digit:
3
✔ Answer:
3
---
🧮 Problem 5:
2□ - 12 = 15
Find the missing digit in the ones place of the top number.
- Inverse: Add 12 to 15 → `15 + 12 = 27`
- So the top number is
27
- Missing digit:
7
✔ Answer:
7
---
🧮 Problem 6:
7□ - 43 = 32
Find the missing digit in the ones place of the top number.
- Inverse: Add 43 to 32 → `32 + 43 = 75`
- So the top number is
75
- Missing digit:
5
✔ Answer:
5
---
🧮 Problem 7:
□1 - 41 = 10
Find the missing digit in the tens place of the top number.
- Inverse: Add 41 to 10 → `10 + 41 = 51`
- So the top number is
51
- Missing digit:
5
✔ Answer:
5
---
🧮 Problem 8:
□9 - 59 = 0
Find the missing digit in the tens place of the top number.
- Inverse: Add 59 to 0 → `0 + 59 = 59`
- So the top number is
59
- Missing digit:
5
✔ Answer:
5
---
🧮 Problem 9:
21 + 4□ = 65
Find the missing digit in the ones place of the second number.
- Inverse: Subtract 21 from 65 → `65 - 21 = 44`
- So the second number is
44
- Missing digit:
4
✔ Answer:
4
