## 305 worked examples and 10 chapters, the video tutor provides a comprehensive review of pre algebra, with carefully selected problems and solutions

This video series is entitled, "Pre Algebra Chapter Test Prep," presented by bob, and with 305 worked examples and 10 chapters, the video tutor provides a comprehensive review of pre algebra, with carefully selected problems and solutions. The series presents 305 individual examples organized over 10 chapters and span the subject of Pre Algebra. These videos have a total playtime duration of 6 hrs 57 min 37 sec. These videos were based in part on the book entitled, "Prealgebra," written by Elayn Martin-Gay. This book provides a comprehensive review of Pre Algebra suitable for elementary school and higher level classrooms.

These tutor videos address all major topics of the textbook in the proper order. Although these video exorcises were designed specifically for this textbook, they apply equally well to any Pre Algebra textbook. This is a fantastic resource for anyone studying Pre Algebra or seeking a well organized, systematic and all encompasing quick review, with or without any particular Pre Algebra textbook. Note that each video clip is very short about 1 minute and typically covers one worked example each, step-by-step. All together these video examples add up to 9 hrs 37 min long of pure math tutoring. If you don't find the particular math problem you're looking for, try other Pre Algebra video tutor sets. Remember my advice? Jump to Chapter: one, two, three, four, five, six, seven, eight, nine, or ten.
