Introduction and Table of Contents

This video series is entitled, "Khan´s Pre Algebra," which provides math help review tutor, examples, problems and solutions, video solution manual. The series presents 39 individual tutorials and span the subject of Pre Algebra. These videos have a total playtime duration of 5 hrs 29 min 27 sec.

This video series on PreAlgebra is from Khan's Academy and provides a brief video lecture review of essential aspects of basic math one should fully understand before advancing to Algebra I (also known as College Algebra). You can skip the parts you find to be too easy if you want. However, I would suggest at least listening to all of it while you do other homework. That way the occasional important bit may grab your attention. And you can easily glide past the parts too basic, without missing anything. All together this runs about 5 hr 29 min 27 sec long.

Even better, I suggest working all the problems mentioned before the speaker solves them. If all the problems are easy, then it should be quick. If you can do so correctly, you will know, with certainty, you are ready to advance. And at any rate (no pun intended), the more problems you actually work, the better you get, the faster you get, and the smarter you will be. Remember my advice.
