You need to make it so that the sum in every row and column will be equal. To do that, you need to select two positive integers. The only numbers that you can place in the grid are those two integers, their sum, their difference, their product, or their quotient. You can place only whole numbers.

Can you complete the grid?

Close, but not quite it. Choosing the integers 3 and 13 as distributed above makes all but two of the rows and columns to add up to 111.  Row 4 and Column 6 adds only up to 110.  Perhaps Charlie is coding a program that will iterate through the possible combinations.

13, 13, 13, 10, 13, 49

16,  3, 17,  3, 39, 10

24,  3,  3, 39,  3, 13

16, 16, 16, 39,  7, 16

10, 43, 13,  3, 16, 10

16,  3, 39, 10, 10,  3
