Combining Like Terms and the Distributive Property

Mrs. Stoner reviews combining like terms and the distributive property in algebra. She explains how to distribute numbers across terms in expressions and how to combine like terms by identifying terms with the same variables and exponents. The video includes examples of simplifying expressions, handling negative signs, and emphasizes the importance of following the order of operations (PEMDAS) in algebraic expressions.
