Pre-Algebra

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.
