Order of Operations and Expressions

Mr. Buckington teaches how to compare mathematical expressions using symbols like less than, greater than, and equal to. The lesson covers solving expressions with order of operations, including examples with basic, advanced, and complex expressions. It also explains how to handle fractions and open sentences by substituting values to find solutions.
