More Information
Open or CloseAn alternative to buying DVDs is to purchase and download the Videos On Demand (VOD). They are a bit cheaper, and you don't have to pay for postage or wait several days for the lessons to arrive. The quality of the video is a bit inferior to the DVD, but not by much. You DO NOT get the PDF Math notes with these files. Those are included free with the DVDs or you can purchase separately at my PDF Printshop. You also do not get the video in multiple formats (AppleTV, iPhone, iPod, etc.) as you would with the DVD version.
NOTE: Teachers and tutors who wish to use my videos for teaching purposes should buy the DVD, not the VOD, of each math lesson. No other school license is needed.
Privacy Policy: Any and all information you provide will be kept private. I will not sell or use your private information in any way.
Download Information: Most downloads are VERY large files (over 1GB in size!), so be sure you have adequate free space on your computer (or external memory) to save files. File size is mentioned in product description. I do not recommend downloading to your mobile device. The DVDs contain smaller versions of the videos that don’t take up much space on an iPhone/iPod.
Terms & Conditions: Please contact FastSpring Support if you encounter problems with your downloads. I describe in detail what is covered in each lesson and provide sample videos elsewhere on this website for you to watch; therefore, there are NO REFUNDS for downloads purchased. You are responsible in deciding what you want. You are given many chances to download the files (usually 612 attempts) and you have 7 days to complete the download. 
Video Brain Teasers Collection
Open or CloseVideo Brain Teasers Collection
This is a collection of the first 58 Video Brain Teasers that have been posted individually on this website (and elsewhere). These consist of recreational mental puzzles/problems dealing with the arrangement of matchsticks, coins, and other items. Also included is a pencil drawing game, a riddle, many Optical Illusions, a "Hidden Image" problem, a "Lateral Thinking" puzzle, and quite a few "Find the Twin" problems.
The puzzles in this video do not have the background music like the individual ones seen here.
It does not include the PDFs nor the individual videos in other formats (Get the DVD if you want these extras).

Algebra: Introduction to Algebra
Open or CloseAlgebra: Introduction to Algebra
This lesson consists of providing you with a SelfTutorial on what is algebra, what are variables, constants, coefficients, terms, and expressions. The tutor explains the use of proper notation, how to combine like terms, find the negation of an algebraic expression, how to evaluate an expression (by hand and by using your calculator), and finally, there is a VERY detailed section on how to translate English phrases into algebraic expressions.

Algebra: Solving Linear Equations, Part 1: The Basics
Open or CloseAlgebra: Solving Linear Equations, Part 1: The Basics
Part 1 of 2. Lesson consists of providing you with a SelfTutorial on how to solve linear equations. Tutor discusses what is an Equation, Solution, Solution Set, Equivalent Equations, Identity, Contradictions, Conditional Equations, Linear Equations, the Standard Form of a Linear Equation. I show you how to actually SOLVE linear equations going stepbystep. I don't skip steps. I review some of the properties of Equality here too. I remind you to check the work done and how to solve linear equations using a calculator. At the end, you will know how to easily solve equations that look like: 2[y  (4y  1)] = 5  9y No word problems are done here. This is shown in DETAIL in Part 2 of the Lesson.

Algebra: Solving Linear Equations, Part 2A: Applications
Open or CloseAlgebra: Solving Linear Equations, Part 2A: Applications
Part 2A (NOTE: You need to get 2B below to have the complete "Part 2" Lesson). This lesson consists of providing you with a SelfTutorial on how to solve typical linear word problems (story problems or applied problems). The tutor shows you how to solve for a specific variable in formulas. He also discusses how to covert a repeating decimal into a fraction (which was skipped in Basic Math: Lesson 6 "Fractions") and will teach you how to convert units of measurement. Examples of word problems done include: Finding a number based on certain criteria. Word problems involving some geometry (triangle, rectangle, circle). Age problems. Mixture problems. Money problems (story of my life!). RateTimeDistance problems. Percent Equations/problems. Ratio and Proportion (concepts and solving problems, including similar triangles). Problems dealing with Unit Price.

Algebra: Solving Linear Inequalities  D1
Open or CloseAlgebra: Solving Linear Inequalities  D1
This is "Disc 1" (D1) of Lesson. It contains the complete lesson, but no "Lesson Quiz." For that, please purchase "Disc 2" (D2) below. This lesson consists of providing you with a SelfTutorial on how to solve typical linear inequalities of the form: ax + b > c (any of these symbols: <, >, ≤, ≥ can be used). The tutor goes over how to draw number line graphs. Also covered is the Double Inequality (a < x < b). Properties of Inequalities are reviewed. Answers are presented in Inequality Notation, Interval Notation, and Set Notation. Compound Linear Inequalities are solved and graphed. Finally, English Phrases are translated into inequalities and some Word Problems are solved.
