This lesson will be on variables. Of course algebra is different than basic math because we often work with variables and not just numbers. Knowing how to work with variables is absolutely critical to master algebra. In this lesson you will learn the parts of a variable term and how to evaluate a variable expression. Please pay special attention to evaluating a variable expression with negative values as many students make errors with this task.
