This lesson is on simplifying like terms. Your main objective in this lesson is to learn when and how we add (combine) variable terms. In algebra a term is the most basic part of what we work with. An example of a variable term would be “3x” or “-8y”. What you will learn in the lesson is how to simplify a variable expression by adding terms. Of course, not all variable terms can be added and the lesson will go into detail on how to determine when you can combine variable terms. One special note: make sure you have mastered the rules of Real Numbers (positive and negative numbers) before starting this lesson.
