- Top-left puzzle:
- Row 1: 7 + 5 = 12
- Row 3: 1 + 4 = 5
- Column 1: 7 + 1 = 8
- Column 3: 5 + 4 = 9
- Bottom-right corner: 17 (given)
- Middle cell (row 2, column 2): 8
- Middle cell (row 2, column 4): 6
- Bottom row, column 1: 8
- Bottom row, column 3: 9
- Bottom row, column 4: 17
- Top-right puzzle:
- Row 1: 8 + 4 = 12
- Row 3: 3 + 8 = 11
- Column 1: 8 + 3 = 11
- Column 3: 4 + 8 = 12
- Bottom-right corner: 17 (implied by structure, but not given; actual bottom-right is 17 for top-left only)
- Middle cell (row 2, column 2): 11
- Middle cell (row 2, column 4): 6
- Bottom row, column 1: 11
- Bottom row, column 3: 12
- Bottom row, column 4: 17 (assumed from pattern)
- Bottom-left puzzle:
- Row 1: 5 + 6 = 11
- Row 3: 6 + 5 = 11
- Column 1: 5 + 6 = 11
- Column 3: 6 + 5 = 11
- Bottom-right corner: 22 (given)
- Middle cell (row 2, column 2): 11
- Middle cell (row 2, column 4): 11
- Bottom row, column 1: 11
- Bottom row, column 3: 11
- Bottom row, column 4: 22
- Bottom-right puzzle:
- Row 1: 7 + ? = 11 → ? = 4
- Row 3: 1 + ? = 10 → ? = 9
- Column 1: 7 + 1 = 8
- Column 3: 4 + 9 = 13
- Bottom-right corner: 17 (assumed from pattern)
- Middle cell (row 2, column 2): 8
- Middle cell (row 2, column 4): 9
- Bottom row, column 1: 8
- Bottom row, column 3: 13
- Bottom row, column 4: 17
