Combining Like Terms and Distributive Property Challenge

Mrs. Lyon introduces two key algebraic concepts: combining like terms and the distributive property. She defines terms and like terms, providing examples to illustrate how to identify and combine them. The distributive property is explained as multiplying a number outside parentheses with terms inside. Mrs. Lyon demonstrates how to apply both concepts together, emphasizing the importance of simplifying expressions using the distributive property before combining like terms. The video concludes with a comprehensive example that integrates both concepts.

What defines a 'term' in an algebraic expression?

• A mathematical statement that includes an equals sign
