## Editorial Reviews

NOTE: A FREE, tiny, low-res version of this lesson is on my web site. Purchase the DVD if you want a larger, high quality movie. This is the NTSC version. This lesson consists of giving you the necessary "preliminaries" to do fractions. The tutor explains what are factors, divisors, prime and composite numbers, how to do prime factorization, GCFs, LCMs, multiples, and the rules of divisibility. He also explains how to use your graphing calculator to help you find the GCF, LCM and multiples. ANOTHER NOTE: This disc is meant to be viewed using a DVD player on a WIDESCREEN (16:9 aspect ratio) TV. My videos are NOT meant to be viewed on Standard 4:3 aspect ratio TVs. In fact, The videos were originally meant to be viewed ONLY on computer monitors and iPods, so even on a widescreen TV, you may experience some "cropping" (chopped off portions of the videos). For the best viewing experience, watch the DVDs using DVD software on your computer. Unfortunately, when these videos were made, I used a cheap wireless microphone, so you will hear an occasional "pop" and "buzz" sound when I am talking. I am sorry about this. The disc is not damaged. I have a new microphone now, so new lessons will be of a much higher quality. When sold by Amazon.com, this product will be manufactured on demand using DVD-R recordable media. Amazon.com's standard return policy will apply.

None.
