Order of Operations Practice in Algebra 1

The video tutorial covers the order of operations in algebra, using the mnemonic PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to guide the process. It provides three examples to illustrate the application of these rules, focusing on solving expressions with different combinations of operations, including nested grouping symbols and exponents. The tutorial emphasizes starting with the innermost grouping symbols and following the order of operations to arrive at the correct solution.
