- "Innie" Sum = 45 - (27 + 13) = 5
- "Outie" Sum = 27 + 13 + 14 - 45 = 9

- "Innie" Sum = 45 x N - sum1 ... where sum 1 equals the sum of all complete cages contained within the row, column, or block and N equals the number or rows, columns or blocks
- "Outie" Sum = sum 2 - 45 x N ... where sum 2 equals sum of all intersected cages and N equals the number or rows, columns or blocks

- 27 + A + 24 - B = 45

- B - A = 27 + 24 - 45 = 6

- sum1 = sum of cages before the "Innie"
- sum2 = sum of cages after the "Innie"

- B - A = sum1 + sum2 - 45 ... where sum1 + sum2 > 45
- A - B = 45 - (sum1 + sum2) ... where sum1 + sum2 < 45

- Sum = 19 + 6 + 16 + 28 - 45 = 24
