Order of Operations and Prime Factorization

The video tutorial by Education Galaxy covers the importance of order in mathematical operations, using the PEMDAS acronym to solve expressions correctly. It explains each step of PEMDAS with examples, emphasizing the need to follow the correct order to avoid errors. The tutorial also introduces prime factorization, demonstrating how to break down composite numbers into their prime factors with examples. The video aims to equip viewers with the skills to perform mathematical operations accurately.
