Understand and Find Square Roots

The video tutorial explains the concept of squares and square roots, starting with calculating the area of a square park and finding the side length of a square sitting area. It introduces the square root operation as the inverse of squaring and explains that every square number has two roots, positive and negative, but focuses on positive roots. The video demonstrates finding square roots using repeated subtraction and prime factorization methods, highlighting their applications and limitations.
