Answer

To solve the problem of the student's addition of 4562 and 728, we can break down the solution step by step.

### Step 1: Write the numbers in a column format.
Align the numbers according to their place values:
```
4562
+ 728
```

### Step 2: Add the numbers starting from the rightmost column (units).
- **Units place**: 2 (from 4562) + 8 (from 728) = 10
- Write down 0 and carry over 1 to the next column.

### Step 3: Move to the next column (tens place).
- **Tens place**: 6 (from 4562) + 2 (from 728) + 1 (carry over) = 9
- Write down 9.

### Step 4: Move to the next column (hundreds place).
- **Hundreds place**: 5 (from 4562) + 7 (from 728) = 12
- Write down 2 and carry over 1 to the next column.

### Step 5: Move to the next column (thousands place).
- **Thousands place**: 4 (from 4562) + 1 (carry over) = 5
- Write down 5.

### Step 6: Write down the final result.
Combining all the digits we wrote down, we get:
```
4562
+ 728
-------
5290
```
So, the correct answer is **5290**.

### Summary of the Solution:
The student lacks understanding of the **place value** concept, which is crucial for performing addition correctly. They did not align the numbers properly according to their place values, leading to an incorrect answer.
