my own way to multiply 3 digit number with 3 digit number fast, please thumb up for every one to see this:
I will use symbols to make it more clear the two numbers are: xyz and abc
xyz*abc
solution:
first digit= x*a (sooo simple isn't it?:D)
second digit= (x*b)+(y*a) just like the foil method
third digit= (x*c)+(z*a)+(y*b) this one is little tricky :)
fourth digit= (y*c)+(z*b) foil method
fifth digit=z*c
of course this will be nothing in front of this genius way but it also solves very fast

Dear rockvsaustinwm26, glad that I could help. Somebody has posted a comment below saying that I have just "Humanised" Mathematics. That's it. Though he said it sarcastically but it is by far the best compliment I have received as a Math teacher.

@FionnMarr, this simple technique ( Rainbow Multiplication ) is deceptively powerful. Once you have mastered it then you can multiply any numbers easily. To see this technique in action watch my Live Seminar video I have uploaded. Click on my name (glad2teach), the name of that video is " Teaching to be Super-Sonic at Math"
