Section 1: Addition

We need to add the numbers vertically for each problem. Here are the steps:

#### Problems:
1. \( 2 + 7 \)
2. \( 4 + 5 \)
3. \( 0 + 6 \)
4. \( 6 + 3 \)
5. \( 8 + 3 \)
6. \( 9 + 2 \)
7. \( 1 + 5 \)
8. \( 2 + 3 \)
9. \( 5 + 0 \)
10. \( 3 + 5 \)
11. \( 3 + 8 \)
12. \( 8 + 7 \)
13. \( 7 + 7 \)
14. \( 9 + 4 \)
15. \( 3 + 3 \)

#### Solutions:
1. \( 2 + 7 = 9 \)
2. \( 4 + 5 = 9 \)
3. \( 0 + 6 = 6 \)
4. \( 6 + 3 = 9 \)
5. \( 8 + 3 = 11 \)
6. \( 9 + 2 = 11 \)
7. \( 1 + 5 = 6 \)
8. \( 2 + 3 = 5 \)
9. \( 5 + 0 = 5 \)
10. \( 3 + 5 = 8 \)
11. \( 3 + 8 = 11 \)
12. \( 8 + 7 = 15 \)
13. \( 7 + 7 = 14 \)
14. \( 9 + 4 = 13 \)
15. \( 3 + 3 = 6 \)

Section 2: Subtraction

We need to subtract the numbers vertically for each problem. Here are the steps:

#### Problems:
1. \( 4 - 2 \)
2. \( 9 - 4 \)
3. \( 2 - 2 \)
4. \( 7 - 0 \)
5. \( 4 - 1 \)
6. \( 8 - 4 \)
7. \( 6 - 3 \)
8. \( 9 - 2 \)
9. \( 1 - 1 \)
10. \( 6 - 5 \)

#### Solutions:
1. \( 4 - 2 = 2 \)
2. \( 9 - 4 = 5 \)
3. \( 2 - 2 = 0 \)
4. \( 7 - 0 = 7 \)
5. \( 4 - 1 = 3 \)
6. \( 8 - 4 = 4 \)
7. \( 6 - 3 = 3 \)
8. \( 9 - 2 = 7 \)
9. \( 1 - 1 = 0 \)
10. \( 6 - 5 = 1 \)
