We've all seen videos or maybe have heard about people who can do large equations in their heads and do it just as fast or faster than a calculator?
I know I've wondered how in the world they do this... Not sure if this is the only method or not, but it seems Mike Byster has found a way and he's
offering to teach it to people, which I find to be quite noble... Wish I had him around when I was in high school or grade school... I would have been
much better at math...
If you want to e-mail Mike visit his
home page. You can also arrange for him to visit your school which I
believe he does for free...
More information on Mike...
