Let’s solve each addition problem one by one. All of these are “adding 1” to a single-digit number. That means we just count up by one from the first number.
Left column:
- 9 + 1 = 10 → because after 9 comes 10
- 2 + 1 = 3 → after 2 is 3
- 4 + 1 = 5 → after 4 is 5
- 8 + 1 = 9 → after 8 is 9
- 3 + 1 = 4 → after 3 is 4
- 0 + 1 = 1 → after 0 is 1
- 5 + 1 = 6 → after 5 is 6
- 7 + 1 = 8 → after 7 is 8
- 3 + 1 = 4 → same as before, after 3 is 4
- 1 + 1 = 2 → after 1 is 2
Right column:
- 2 + 1 = 3 → after 2 is 3
- 5 + 1 = 6 → after 5 is 6
- 0 + 1 = 1 → after 0 is 1
- 6 + 1 = 7 → after 6 is 7
- 8 + 1 = 9 → after 8 is 9
- 1 + 1 = 2 → after 1 is 2
- 4 + 1 = 5 → after 4 is 5
- 3 + 1 = 4 → after 3 is 4
- 9 + 1 = 10 → after 9 is 10
- 7 + 1 = 8 → after 7 is 8
All answers checked and verified.
Final Answer:
Left column: 10, 3, 5, 9, 4, 1, 6, 8, 4, 2
Right column: 3, 6, 1, 7, 9, 2, 5, 4, 10, 8
