This puzzle follows a pattern where the result is based on subtracting the sum of the digits of the product from the product itself.
For example:
For \(84 \times 13 = 8\), the product is 1092, and the sum of its digits is \(1 + 0 + 9 + 2 = 12\), then \(1092 - 12 = 8\).
Similarly for \(56 \times 22 = 1232\), the sum of its digits is \(1 + 2 + 3 + 2 = 8\), and \(1232 - 8 = 36\).
Thus, the correct answer is "36."
