Combining Like Terms in Algebra

This video tutorial explains how to simplify algebraic expressions by combining like terms. It begins with defining what a term is and how like terms have matching variables and exponents. The video provides examples to demonstrate how to add coefficients of like terms and simplify expressions. It emphasizes that terms can only be combined if their variables and exponents match, and provides step-by-step examples to illustrate the process.
