Order of Operations and Expressions

The video tutorial explains how to simplify an expression using the order of operations. It begins with an introduction to the concept, followed by simplifying expressions with exponents. The tutorial then covers multiplication and division from left to right, and concludes with the final calculation and verification using a graphing calculator. The expression simplifies to -7, and the process is verified for accuracy.
