Order of Operations and Exponents

The video tutorial explains how to evaluate and simplify mathematical expressions using the order of operations. It covers two expressions: the first involves simplifying within parentheses and then squaring the result, while the second involves squaring individual terms and then adding them. The tutorial emphasizes the importance of following the correct order of operations to achieve accurate results.
