Simplifying Expressions: Combining Like Terms

This video lesson on algebra focuses on combining like terms and understanding algebraic properties. It covers key vocabulary such as variables, coefficients, and constants, and provides examples of simplifying expressions by combining like terms. The lesson also discusses unlike terms, constant terms, and how to handle positive and negative integers in expressions. Students are encouraged to practice these concepts through examples and exercises.
