Exploring Parts of an Expression

This video tutorial covers the parts of an algebraic expression, including terms, coefficients, constants, and like terms. It explains how to identify these components and use properties to simplify expressions. The video provides examples of simplifying expressions, including those with negative terms, and concludes with a practice problem for viewers to try on their own.
