Mr. McKeague's Math TV

Charles P. "Pat" McKeague is owner of MathTV.com. He's a mathematician (with a B.A. and M.S. in the field), college instructor, published author of math textbooks (covering everything from basic mathematics to trigonometry) and a speaker at mathematics conferences in California and nationwide.

He's also an excellent teacher who provides clear instructions on how to solve math problems as well as bits of life philosophy, like: Do something for the person you will be 5 years from now.

His website, MathTV.com, doesn't even require you to register -- you can start viewing the instructional videos (given by Mr. McKeague and student instructors) right away, or print out textbooks and practice tests.

Take a moment to explore the site in order to reap full benefits. If you need help with long division, for example, you click on Basic Mathematics, then Whole Numbers, then Dividing. Once you get there, you can choose which long division problem you'd like to see solved: if you want to start with a one-digit divisor, try 595/7; for a two-digit divisor, there's 9,380/35. You may prefer one instructor's style to another: I found Katrina a much more thorough teacher than Aaron, although Aaron is fine for a quick review.

If you wish to factor rational expressions to their simplest forms, look under the Algebra topic heading. Radians and degrees are found under Trigonometry, with perimeters, parallelograms and congruent triangles all found under Geometry.

Tip: full screen view makes the videos easier to see and you just press your ESC key to return to Normal Screen.

Long Division

Long division (called the algorithmic process) is the next on my list -- I mean, my kid's list -- to learn.

The standard approach to solving long division is broken down into five steps:

1. Divide
2. Multiply
3. Subtract
4. Bring Down
5. Repeat (if necessary)

In case you need a bit of a refresher, here are a few sites that explain and illustrate the process:

• the Long Division page at Math is Fun

• the Long Division page at AAA Math

• the Long Division lesson at Cool Math 4 Kids (you can test your skills at their Number Monster page)

DoubleDivision.org is a site that introduces a different method of doing long division and has an easy-to-understand calculator that works the problem through with you step by step. Instead of five steps, double division has three:

Step 1 - Double, double, double.
Step 2 - Subtract off multiples.
Step 3 - Add up your answer.

The benefit of this system over the five-step system is said to be that

double division does not depend on memorizing the multiplication facts or estimating how many times one number goes into another. It may take 50% longer, but it is far less frustrating and probably easier to understand than long division.

Whatever works works for me!
