Follow Order of Operations | 14 Examples

The video tutorial covers the importance of using the order of operations, often remembered by the acronym PEMDAS, to ensure consistent results in mathematical expressions. The instructor explains common confusions, such as the misconception that multiplication always precedes division, and emphasizes the left-to-right rule for operations of the same precedence. Through a series of examples, the tutorial demonstrates how to apply these rules, including handling complex expressions with parentheses, exponents, and fractions. The video concludes with a call to explore further examples and resources.
