  Its amazing i am a 10 grade dropout that made C&apos;s, D&apos;s and F&apos;s in math, i could never retain what teachers where trying to teach in school with chalk bored methods, it would take me weeks to drill much more basic mathematics than this into my head using typical teaching methods but i pretty much retained and understand everything in this video in 9 minutes at worst watching it 1-2 more times would be perfect. Its amazing with videos like this i could learn everything from 1st-12th grade and on into collage level in less than a year by these standards i only wish i was about 10 years ahead so i could have had access to this stuff when i needed it most, textbooks and teachers did not cut it for me all i needed was the ability to have problems visualized in front of me in a clean simple manner at a pace i can handle with the ability to pause, rewind as i please. And i know i must not be the only person that was like myself that has found this way to be ten times more effective.
