# Pre-Algebra

Thinkwell's Pre-Algebra is designed for college and high school students who are preparing for algebra. This course features online videos by award-winning Professor and mathematician Edward Burger who uses example-based tutorials that break Pre-Algebra into the basics, giving students the tips and tricks they need to excel at algebra. Students practice their newly acquired skills with automatically graded online exercises and get step-by-step explanations and answer solutions.

Thinkwell's Pre-Algebra covers the same topics that are in every pre-algebra textbook, so it's easy to use as a study aid. Because it's available any time, day or night, and you only pay one flat fee for 12 months of access, not by the hour, it's better than a pre-algebra tutor.

**Our complete Pre-Algebra package includes:**

- 12-month Online Subscription to our complete Pre-Algebra course with video lessons, automatically graded exercises, and much more.
- Workbook (optional) with lecture notes, sample problems, and exercises so that you can study even when away from the computer.
