Analysis
Because the table has 2 rows and 3 columns, and 1+2+3+5+6+7=24, the sum of the three numbers in each row is 24÷2=12. Thus, these six numbers can be divided into two groups: (7,3,2) and (6,5,1). Similarly, based on the given conditions, the sum of the two numbers in each column is 24÷3=8. We need to consider both the condition that the sum of the 3 numbers in each row is equal and the condition that the sum of the 2 numbers in each column is equal. After attempting, we can obtain the following 12 answers.
