Distributive Property and Combining Like Terms Explained

Maria, a mathematician, explains how to simplify expressions using the distributive property and combining like terms. She demonstrates with an example, showing how to distribute a number across terms in parentheses and then combine like terms by focusing on their coefficients. The video concludes with a simplified expression and a recap of the steps involved.
