To solve the problem, we need to find the missing addend in each equation. The missing addend is the number that, when added to the given number, results in the sum provided. Let's solve each equation step by step.
Left Column:
1.
47 + ☐ = 51
- Subtract 47 from 51: \( 51 - 47 = 4 \)
- Missing addend:
4
2.
22 + ☐ = 27
- Subtract 22 from 27: \( 27 - 22 = 5 \)
- Missing addend:
5
3.
34 + ☐ = 41
- Subtract 34 from 41: \( 41 - 34 = 7 \)
- Missing addend:
7
4.
54 + ☐ = 62
- Subtract 54 from 62: \( 62 - 54 = 8 \)
- Missing addend:
8
5.
37 + ☐ = 40
- Subtract 37 from 40: \( 40 - 37 = 3 \)
- Missing addend:
3
6.
78 + ☐ = 82
- Subtract 78 from 82: \( 82 - 78 = 4 \)
- Missing addend:
4
7.
66 + ☐ = 71
- Subtract 66 from 71: \( 71 - 66 = 5 \)
- Missing addend:
5
8.
44 + ☐ = 50
- Subtract 44 from 50: \( 50 - 44 = 6 \)
- Missing addend:
6
Right Column:
9.
☐ + 29 = 34
- Subtract 29 from 34: \( 34 - 29 = 5 \)
- Missing addend:
5
10.
☐ + 44 = 48
- Subtract 44 from 48: \( 48 - 44 = 4 \)
- Missing addend:
4
11.
☐ + 62 = 67
- Subtract 62 from 67: \( 67 - 62 = 5 \)
- Missing addend:
5
12.
☐ + 17 = 22
- Subtract 17 from 22: \( 22 - 17 = 5 \)
- Missing addend:
5
13.
☐ + 83 = 89
- Subtract 83 from 89: \( 89 - 83 = 6 \)
- Missing addend:
6
14.
☐ + 37 = 43
- Subtract 37 from 43: \( 43 - 37 = 6 \)
- Missing addend:
6
15.
☐ + 48 = 54
- Subtract 48 from 54: \( 54 - 48 = 6 \)
- Missing addend:
6
16.
☐ + 15 = 21
- Subtract 15 from 21: \( 21 - 15 = 6 \)
- Missing addend:
6
