The baker did the wrong way of solving the problem. When he "tried" to add the numbers up the other guy who was saying he was wrong added all the numbers on the right side. Then, the baker added all the numbers on the left side to the total from the right. Some numbers that would work for this are: 3 and 17, 6 and 12,and 4 and 18. These were some of the numbers I found that worked.
