I will take that back. This method works great..i got it to work for 3672 x 3672 as well..i was doing incorrect additions.

Tried…it works fine..i think we really have to understand the rules of addition when we r multiplying higher numbers with another higher number..like i could not figure out how to do 3672 x 3672…

You could always do …
You could always do it recursively. Just multiply the first pair using this method, then multiply that product with the third number. Although I wonder if it could be extended to a three-dimensional space…

Hmm, very …
Hmm, very interesting method, although I’d like to see it done with a pair of very large random numbers. Also, I thought the symmetry of 123×321 was a poor choice for a demonstration.

simple we carry the …
simple we carry the 1 across because it belongs to a higher number placement. for example: 78 = 78 ones OR 7 tens and 8 ones, whereby 7 is the higher number placement.
