Let’s solve each problem one by one. We’re looking for the number that, when added to the given number, equals 10.
We’ll go row by row, left column first, then right column.
---
Left Column:
1. 4 + □ = 10 → What plus 4 is 10?
10 - 4 = 6 → So,
6
2. □ + 3 = 10 → What plus 3 is 10?
10 - 3 = 7 → So,
7
3. 8 + □ = 10 → What plus 8 is 10?
10 - 8 = 2 → So,
2
4. □ + 6 = 10 → What plus 6 is 10?
10 - 6 = 4 → So,
4
5. 5 + □ = 10 → What plus 5 is 10?
10 - 5 = 5 → So,
5
6. □ + 9 = 10 → What plus 9 is 10?
10 - 9 = 1 → So,
1
7. 7 + □ = 10 → What plus 7 is 10?
10 - 7 = 3 → So,
3
8. □ + 1 = 10 → What plus 1 is 10?
10 - 1 = 9 → So,
9
9. 10 + □ = 10 → What plus 10 is 10?
10 - 10 = 0 → So,
0
10. □ + 5 = 10 → What plus 5 is 10?
10 - 5 = 5 → So,
5
11. 2 + □ = 10 → What plus 2 is 10?
10 - 2 = 8 → So,
8
12. □ + 0 = 10 → What plus 0 is 10?
10 - 0 = 10 → So,
10

Right Column:
1. 2 + □ = 10 → What plus 2 is 10?
10 - 2 = 8 → So,
8
2. □ + 4 = 10 → What plus 4 is 10?
10 - 4 = 6 → So,
6
3. 6 + □ = 10 → What plus 6 is 10?
10 - 6 = 4 → So,
4
4. □ + 8 = 10 → What plus 8 is 10?
10 - 8 = 2 → So,
2
5. 5 + □ = 10 → What plus 5 is 10?
10 - 5 = 5 → So,
5
6. □ + 0 = 10 → What plus 0 is 10?
10 - 0 = 10 → So,
10
7. 1 + □ = 10 → What plus 1 is 10?
10 - 1 = 9 → So,
9
8. □ + 3 = 10 → What plus 3 is 10?
10 - 3 = 7 → So,
7
9. 5 + □ = 10 → What plus 5 is 10?
10 - 5 = 5 → So,
5
10. □ + 7 = 10 → What plus 7 is 10?
10 - 7 = 3 → So,
3
11. 9 + □ = 10 → What plus 9 is 10?
10 - 9 = 1 → So,
1
12. □ + 10 = 10 → What plus 10 is 10?
10 - 10 = 0 → So,
0

Now let’s write all answers in order, matching the boxes from top to bottom, left to right.
Left column answers (top to bottom):
6, 7, 2, 4, 5, 1, 3, 9, 0, 5, 8, 10
Right column answers (top to bottom):
8, 6, 4, 2, 5, 10, 9, 7, 5, 3, 1, 0
Final Answer:
Left Column: 6, 7, 2, 4, 5, 1, 3, 9, 0, 5, 8, 10
Right Column: 8, 6, 4, 2, 5, 10, 9, 7, 5, 3, 1, 0
