Pre-algebra
Thinkwell's Pre-Algebra is designed for college and high school students who are preparing for algebra. Students love to learn Pre-Algebra online with videos and automatically graded Pre-Algebra problems. Award-winning Professor Edward Burger uses example-based tutorials that break Pre-Algebra into the basics, giving students the tips and tricks they need to excel at algebra.
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.
