Order of Operations and Exponents

The video tutorial introduces the concept of order of operations in mathematics, using the mnemonic 'Please Excuse My Dear Aunt Sally' to explain the sequence: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Two example problems are solved step-by-step to demonstrate the application of these rules. The tutorial emphasizes the importance of following the correct order to achieve accurate results.
