Explanation of Solutions
1.
Addition Problems:
- To solve addition problems (e.g., \( 7 + 2 \)), simply combine the two numbers.
- Example: \( 7 + 2 = 9 \).
2.
Subtraction Problems:
- To solve subtraction problems (e.g., \( 13 - 8 \)), take the second number away from the first.
- Example: \( 13 - 8 = 5 \).
3.
Carrying Over or Borrowing:
- For larger numbers, ensure you carry over or borrow as needed.
- Example: In \( 14 - 7 \), no borrowing is needed since \( 14 \) is greater than \( 7 \).
4.
Step-by-Step Calculation:
- Perform each operation carefully to avoid mistakes.
- Example: For \( 18 - 9 \), subtract \( 9 \) from \( 18 \) to get \( 9 \).

Final Answer
The solutions to all the problems are as follows:
| Row 1 | Row 2 | Row 3 | Row 4 | Row 5 |
|-------|-------|-------|-------|-------|
| 5 | 12 | 8 | 4 | 4 |
| 9 | 7 | 1 | 15 | 9 |
| 2 | 15 | 7 | 8 | 8 |
| 9 | 2 | 9 | 13 | 11 |
| 10 | 3 | 6 | 6 | 6 |
| 11 | 8 | 6 | 5 | 8 |
| 12 | 9 | 4 | 6 | 8 |
| 12 | 2 | 1 | 11 | 8 |
| 9 | | 10 | 4 | |
Thus, the final boxed answer is:
\[
\boxed{5, 9, 2, 9, 10, 11, 12, 12, 9, 12, 7, 15, 2, 3, 8, 9, 6, 4, 1, 2, 8, 1, 10, 4, 15, 8, 8, 13, 6, 11, 4, 6, 6, 8}
\]
