Hello... I just got through watching a infomercial on 
'Mathemagics'. Basically, the creators of this program say that if 
you buy their product, it will teach you how to do complex math 
problems in your head.  Like multipying any size numbers together, 
or dividing any two numbers. And it says it will teach you how to 
do this 'faster than a calculator'. 

I was wondering if you might know how some of these feats are 
done? And, if you do know, perhaps you might enlighten me a little 
bit. 

Thanks in advance..

You'll find tips and tricks for dividing by numbers from 3 to 11, 
and a series of calculation hints from the BEATCALC mailing list.
