Video Summary

The problem involves assigning distinct positive integers to different animals such that the sum in each column's top and bottom rows equals the given sum for that column. The goal is to maximize the sum of the four integers in the first row. By assigning the highest possible numbers to the top row while following the column constraints (sums of 3, 7, 11, and 15), the integers assigned are 2, 4, 6, and 8. This results in the largest possible sum of 20 for the top row. Hence, the maximal sum is 20.
