AWESOME! This is really useful :)
Ok, now do 987 x 998...
This video assumes you know how to count. :D
not bad.. but if you actually think about it, all you're really doing is the paper method, except instead of using numbers
i.e. to do AB x CD by hand, you multiply D by A, then D by B, then C by A, then C by B. But since C is in the 10s and D is in the 1s, you move C over by 1. Then you add them together.
When the person draws the line, the leftmost digit is drawn to the top or left, which is like moving "C over by 1". Every time each line crosses, it's just like multiplying D x A, D x B, etc etc. =)
Very Interesting!
I want to see 655463723x937574737 done in this manner though.
614546227704765851 is the answer...
Scan the lines for me later. ha ha...
ha ha ha... I would do it but I can only count up to 614546227704765850... so it's a no go...
Thats interesting, but I felt the last multiplication problem, I would be able to answer it faster the traditional way, instead of drawing lines.
That's pretty incredible.
Creative and awesome ... wonder can i use this method in exam?
Show that you have to think out of the box. Why didn't we learn that in school?
Ilker:
"How To Multiply Large Numbers Creatively" may have been a better title...what's easy about that?
I'll tell you how to multiply large numbers easily, "Honey...get me my calculator!"
;-)
Same here Ilker, as soon as counting gets complicated, my calculator is out.
What do you think? Post your thoughts..
