This lesson focuses on combining like terms to simplify expressions. The instructor introduces the concept of adding negative numbers to change all subtractions to additions, allowing for the commutative property to be used. The lesson also covers the importance of identifying and grouping like terms and applying the distributive property. Students are encouraged to practice these skills to apply them to more complex problems in the future.
Learn what it means for an expression to have like terms and how to combine like terms to simplify.
