Unsurprisingly, I don't understand the entire procedure. Well I might if I tried, but you know. I'm not used to having to think things through.

I'd never heard of this technique before, but it seems like an incredibly easy way to calculate the results of large multiplications: http://www.metacafe.com/watch/296904/easy_mental_multiplication_trick//R/ffd_201 |

I was watching it, but then i noticed that the second calculation was taking aaaaages. Then I looked down at the comments and someone pointed out that he was using digits no bigger than 3. Turns out to be very impractical. |

I just did it with 568*345. It becomes more work but not as tedious as I expected. Off course, it's less work to multiply each number and add the results, but I like connections between plain boring maths and visual representations of it. |
