Add the numbers on either side then take the product of the 2 digits of the result.
So:
18 + 5 = 23; 2 * 3 = 6.
24 + 37 = 61; 6 * 1 = 6
8 + 8 = 16; 6 * 1 = 6
10 + 22 = 32; 3 * 2 = 6.
Puzzle B: the answer is 12.
The product of the 2 numbers then the product of the digits of the result.
13 * 2 = 26; 2 * 6 = 12
2 * 31 = 62; 6 * 2 = 12
17 * 2 = 34; 3 * 4 = 12
43 * 1 = 43; 4 * 3 = 12
