Order of Operations and Basic Arithmetic

The video tutorial introduces the concept of order of operations, commonly known as PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It explains the importance of following this order when solving mathematical expressions. The tutorial includes example problems to demonstrate how to apply these rules, such as calculating calories burned and evaluating complex expressions. The video concludes with guided practice to reinforce the learning objectives.
