It looks like you've uploaded a set of worksheets focused on
adding and subtracting 4-digit numbers using different methods, including
column addition/subtraction,
using the inverse operation, and
problems involving exchanging (regrouping).
However, since I cannot view or access images directly, I can't see the specific problems or tasks in your image. But based on the visible titles and layout, here’s how I can help:

🔍 What I Can Help With:
If you describe the
specific problem(s) from the worksheet (e.g., “Problem 5: 3254 + 4071” or “Subtract 2877 from 5648”), I can:
- Solve it step-by-step.
- Explain the method used (e.g., column method, regrouping, inverse check).
- Show how to verify the answer.

✔ Common Types of Problems on These Sheets:
Here are typical examples and how they're solved:
#### 1.
Adding 4-Digit Numbers (Column Method)
Example:
```
3254
+ 4071
------
```
Step-by-step:
- Add units: 4 + 1 = 5
- Tens: 5 + 7 = 12 → write 2, carry 1
- Hundreds: 2 + 0 + 1 (carry) = 3
- Thousands: 3 + 4 = 7
Answer:
7325

#### 2.
Subtracting with Exchanging (Regrouping)
Example:
```
5648
- 2877
------
```
Step-by-step:
- Units: 8 - 7 = 1
- Tens: 4 < 7 → borrow 1 from hundreds → 14 - 7 = 7
- Hundreds: 5 (after borrowing) - 8 → need to borrow from thousands → 15 - 8 = 7
- Thousands: 4 (after borrowing) - 2 = 2
Answer:
2771

#### 3.
Using the Inverse Operation
To check if subtraction is correct, add the result back:
If:
```
5648
- 2877
= 2771
```
Check:
2771 + 2877 = 5648 → Correct!

#### 4.
Mixed Calculations & Challenges
These might include:
- Word problems
- Missing numbers (e.g., ___ + 325 = 5000)
- Using number lines or compensation strategies
