Video Summary

The problem involves ensuring an equal number of trees on both sides of each path in a city park, given one existing tree. Initially, the method involves focusing on one path at a time by temporarily ignoring the other two and observing the tree balance. After adjusting for each path, it is determined that planting three additional trees will achieve the desired balance across all paths. Therefore, the smallest number of trees needed to plant to balance each path is three.
