Amazing New Way to Multiply

Amazing New Way to Multiply by hand:

Just Watch the video this totally amused me!

cool method, but probably extemely time consuming after the number 3. most likely the reason for not using any higher numbers in the video.

That was cool.
But it's quicker with a calculator.

3 Days after the not so distant future:

Let me be the first to say that this will really help me. May be a little time consuming but when i don't have a calculator I'm completely useless at multiplication using any of the standard taught ways.

How was this achieved and who found this out? Problem is like some one said and guessed my self is if you use 9999 x 9999 how many lines are we talking about? But if one is stuck for numbers who knows it could be a great help.

Interesting new method of multiplying, you could use this method OR and this is a big or...you could just multiply it out the old fashioned way.

Thats the problem I have, its very hard for me to multiply in my head or even written down the old fashioned way, they both require multiplying in the head and i just cant do it unless I have a calculator to help me.

The time lord you are right this would be useless for vary large numbers but when it comes to every day use of multiplication it seams to work quite well.

what happens with 10x10 then???

Edn: My brother suffers the same problem, ill bet hell love this
way of doing it.

How come this alternatives are not taught anymore? I mean for kids this would be
a great way to start

Useful technique if going into a home depot and do quick square footage calculations

I did the same thing with 200 X2 i placed dashed lines instead
and whatever is inside the dashed lines is a zero

same video here it made close to $8,000

can anybody make a bmp or something to show the calculations for 105*27 using this method?? I tried and just confused myself..

I was amused and so I looked for some new math trick videos and I found a funny math video: video.google.com...

This may yet look useful: digg.com...

Very interesting but I think I'd do it the old fashioned way even faster. Interestingly, it seems harder for me to do addition and subtraction than multiplication and division. I think it's because I had horrible math teachers in my early years. Calculus was a breeze for me when I was in school (I got a 5 on the AP Calculus BC test in high school), but it still took me some time to make sure any adding and subtracting was correct...
