Order of Operations and Parentheses

The video tutorial explains how to evaluate a mathematical expression using the order of operations. It begins by identifying the innermost grouping symbols, such as parentheses and brackets, and simplifies the expression step by step. The process involves performing multiplication and division before addition and subtraction. The tutorial demonstrates simplifying within parentheses first, followed by brackets, and concludes by verifying the result using a calculator. The final expression simplifies to 156, confirming the correct evaluation.
