## Pre-Algebra Course Outline

The Pre-Algebra course completes the student’s instruction in arithmetic. Students will learn how to work with factors and multiples. The application of percentage and ratios to financial problems will be covered. Algebraic notation and concepts will be introduced in a formal way. This course uses Pre-Algebra by Larson, Boswell, Kanold, & Stiff.
