  • love it

  • it is difficult forrrrr  7, 8 or 9 f. ex. 797 x 979= solve this... B) ummmm 8 second ;-)

  • thanks for sharing...

    this is a brilliant example of lateral thinking!

    especially useful when calculator is not handy

    just like working with abacus is mathematics

    this is another FUN and creative way of solving a mathematical problem - so IT IS MATHEMATICS, no?!

    if multiplication uses straight lines, perhaps division uses circles or triangles going concentrically in or out?!!

    in anticipation of your next creative aha moment

    please take care and keep smiling :))))

  • wait woah woah... i understood it completely until that last moment with the 1 pointing to the 8. whats up with that?

  • @PianoMastR 1+8=9

  • @pajson13 ohh ok i got it. thats really cool :D

  • wow..cool thanks!!!

  • what about division?

  • @felderup No solution yet

  • whabout 999 x 999?

  • wtf man buy caLCULATOR

  • although it takes time 2 draw and using calculator is much more faster but if our calculator run out of battery this trick is very useful....

  • @venturachungcheewoon If calculator ran out of battery, I'd use the normal technique, not drawing..

  • takes too long to draw

  • that is a very cool trick ...

  • Its not new, its ancient. Check out vedic mathematics.

  • yes truying to steal the ancient knowlage, but it doesnt work.

  • that is so cool if our math teacher showed us that at school i would have been more interested

  • @christinepitcher1984 i somehow doubt that otherwise you would have been just as interested when you learned the old way because even though old, it was new to you at some point and it didn't 'interest' you then. Just Saying. PEACE.

  • pretty neat

  • wow great job (does it work with every)

  • yeah thats neat...but doing it the normal way is faster lol

  • well... nice

    you call that "A new kind of mathematic"

    ...but i prefere to call: "GEOMETRY AND Symmetry of the numbers

  • this is Awsome cuz im blah w/numbers ...waay too many of them :I

  • I think this is useful for children!!!

    It's not a trick but it's very helpful

  • DUMB - You just visualized what you do normally anyway. ...

  • Comment removed

  • awesome

  • calculator is much easier XD

  • Comment removed

  • Genuis but it dus not word on all

  • xD coooolll

  • its like pytagolas

  • This is a good method ^^

    But I use a calculator

    XD

  • Clever indeed

  • ^^

    I know xd

  • u have way 2 much time like i do for watching the vid but i get it

  • huh interesting

  • math for dummies... LOL

  • only a really dummie would say that

  • good visualization but it is still not a "trick". ever been to an elementary school dummie!?

  • Awesome!

  • its cool but takes too long

  • Wow! That's great and it only takes about 10 times as long as the normal way! I'm sure the govt will implement it as a way of making people even dumber.

  • animal :)

    have to show this in schol after da tests :)

  • i work at a bank and we have all started to use this method :D dam this is really good and fast

  • uuum yes i like it the way it is thank you

  • Maybe we can pass the hat around and buy pajson13 a calculator for christmas.

  • Hahahaha

  • errr..

  • -.-''

  • That sucks!! use faster and easier ways man.

  • ABOOO DUE SVENSK COOLT

  • it surely works out. But it is even slower than the traditional method {@_@} ?

  • wow interesting..!

  • how do u know where to grooup the intersections

  • This does not work well when you use numbers with higher digits like 99 X 87. It is easier to use other methods then.

  • Well...for 99X87 you just do (100-1) X 87

  • Oh! Is that all you have to do? Wow! I see! Shut up!

  • What a great way to run out of time during your math final. Lame technique.

  • TRUE

  • dude has way to much time

  • thats close to lattice multiplication, xept for lattiice multiplication is way easier

  • just think about doing this with a number like 978 x 759 or some thing. that would just be a ridiculous amount of lines

  • Meh, it's just a visualization of the same exact principles. Perhaps a good teaching tool, though, to get the point across.

  • Amazing, perfect for me, I can't do maths at all!!! You should get a patent on this!!

  • im getting the hang of this already. That's brilliant.

  • it's simple trick.

    mn*pq=(m*p)*100+(m*q+n*p)*10+n­*q*1

    ....

    you just count the number of the point as m*p...

    but you know it will cost a lot of time when you put your finger on the paper.

  • yyes

  • You don`t have to pott youre finger on the papper:P

  • It works... i know.. but what if you

    pick; 48 x 57 then it doesn't work.. right?!

  • yes it work!!! whenever the "number on the inside" is greater than the "number on its right side" than you'll add from right to left the 1st number to its right than the "last number" to its left... (hope this makes is sense) you should have had...48 x 57 = 20, 68, 56 from 48 x 57 right? Take the 5 and add it to 68 (68 + 5= {73} + 0) now your number's are 2, 73, 6 = 2,736 in your answer...

  • hello,erm,i have tried your method and i have a question to ask,what if we face question like 10*1?or maybe even 100*100 and so on and so forth,are you able to ans my question?

  • Great for a design

  • not a good idea for 987 * 789

    then you'll have to draw 9 + 8 + 7 + 7 + 8 + 9 = 48lines

    and count the intersections of these 48 lines :)

  • lol

  • waste time only...

  • lol I still prefer the old method ;p

    nice though

  • Interesting algorithm, but what is the advantage? You could come up with many different methods, but the main end concern is which one works the best right?

  • right its like for the multiplications we could also take the integral of one number from 0 to the other number, and you'd get the same answer :D

  • Huh? Could you elaborate on that?
