About This Lesson
An expression is a mathematical phrase that contains terms that are added and subtracted. A term describes the parts of an expression that are added or subtracted; each term contains two or more factors. A factor is a number that is multiplied by another number or by an expression to make a product. A variable is a letter that is used to
represent a number.
In this module, you will learn and practice the following skills:
- Parse an expression into its different factors, depending on its variables
- Understand how different variables correspond to different quantities and affect the expression as they change in value
