- Row 1, Column 3: 18 - 9 = 9, 12 - 6 = 6, 15 - 6 = 9 → Not all same.
- Row 2, Column 1: 3 + 6 = 9, 14 - 8 = 6, 16 - 7 = 9 → Not all same.
- Row 3, Column 2: 4 + 5 = 9, 7 - 6 = 1, 5 + 8 = 13 → Not all same.
- Diagonal (top-left to bottom-right) in first grid: 8 + 7 = 15, 14 - 8 = 6, 15 - 6 = 9 → Not all same.
- Diagonal (top-right to bottom-left) in first grid: 18 - 9 = 9, 14 - 8 = 6, 16 - 7 = 9 → Not all same.
- Row 1, Column 1 in second grid: 16 - 8 = 8, 5 - 2 = 3, 16 - 9 = 7 → Not all same.
- Row 2, Column 2 in second grid: 4 + 3 = 7, 15 - 9 = 6, 9 + 3 = 12 → Not all same.
- Row 3, Column 3 in second grid: 2 + 9 = 11, 19 - 7 = 12, 16 - 4 = 12 → Not all same.
- Row 1, Column 1 in third grid: 9 + 4 = 13, 18 - 5 = 13, 16 - 3 = 13 → All same! (Answer: 13)
- Row 2, Column 2 in third grid: 12 - 7 = 5, 7 - 6 = 1, 5 + 8 = 13 → Not all same.
- Row 3, Column 3 in third grid: 11 - 6 = 5, 14 + 5 = 19, 16 + 3 = 19 → Not all same.
- Row 1, Column 1 in fourth grid: 11 + 7 = 18, 19 - 3 = 16, 14 + 2 = 16 → Not all same.
- Row 2, Column 2 in fourth grid: 15 + 3 = 18, 9 - 3 = 6, 9 + 3 = 12 → Not all same.
- Row 3, Column 3 in fourth grid: 6 + 6 = 12, 19 - 7 = 12, 16 - 4 = 12 → All same! (Answer: 12)
The rows, columns, or diagonals where all answers are the same are:
- Third grid, Column 1: 9 + 4, 18 - 5, 16 - 3 (all equal 13)
- Fourth grid, Column 3: 6 + 6, 19 - 7, 16 - 4 (all equal 12)
