The video tutorial explains how to estimate square roots to the nearest whole number. It begins with a refresher on basic square roots and then introduces the concept of estimation when an exact whole number square root is not possible. The tutorial provides multiple examples, demonstrating how to determine which whole number a square root is closest to by comparing it to perfect squares. The video concludes with advanced examples and a summary of the estimation process.
