These short lessons are designed to fill in the gaps in understanding of basic mathematical concepts that many very intelligent people missed. The topics covered here were identified in a multi-year research study of students enrolled in college algebra and students being tutored for post-secondary high-stakes math tests. The study found that straightforward explanations of these concepts along with concrete examples resulted in a greater than 90% pass rate. Additionally, some students went on to be successful in majors that required several college-level math classes.
These lessons are designed to be done in order. Even if you think you understand a topic, watch the video anyway because it may show you a new way to look at a topic that makes other things easier. If you are studying for a high-stakes test, take practice tests as you watch these videos.
