Graphical multiplication

This is cool. The video calls is Japanese multiplication, but it would be interesting to find out what branch of mathematics (like topology or something) that this is derived from.

Very cool!

Thanks for sharing Mark. That was very interesting! I am gonna give it a try myself.

Mostly algebra...

21 * 13
(20 + 1) * (10 + 3)
20 * 10 + 20 * 3 + 1 * 10 + 1 * 3
2*1 * 100 + (2*3 + 1*1) * 10 + 1*3 * 1

Ok, it matters apparently where you put those arcs, but how do you determine where they go?

Really cool. I will have to look into this some more.

Blak Smyth · 01-20-2012, 06:41 AM

Wow amazing, gonna try it now!

chaase321 · 01-20-2012, 07:59 AM

Interesting concept...I'm gonna try it out on some new ones and see if it works.

Blak Smyth · 01-20-2012, 08:02 AM

I just blew some peoples minds at work!
They insisted on getting a calculator to double check, it worked multiple times.
Just don't us any 7s, 8s or 9s!!! To many intersections to count!

But I would assume it still works?

Yah I did it with a '6' and it still worked, I had to count it like three times though.
