I don't understand it; thus it is inferior.
13*10=130 --> 130+13+13=156
Desc too long.

I like it.

To simplify the Japanese way, they have lines for the 1 3 and 1 2, and then you draw the circles and oval. You count up how many intersections are in each circle, and that's your number
User avatar #12 - fuckinfuckinfuck ONLINE (09/27/2013) [-]
Or you can just do 13*10 + 13*2...

I'm using a trackpad don't make fun of me
3x2, 2x1 =
drop zero to next level
1x13, put before zero
add products

That's what I was taught at least. That method doesn't require being asian or 3 different colored markers on hand.

We were just taught to memorize all of the numbers..... **** me
User avatar #59 to #9 - soupkittenagain (09/27/2013) [-]
When and where?

Mathematical proof

AB * CD
= (A*10 + B) * (C*10 + D)
= A*C + 10*A*D + 10*B*C + 10*10*A*C
= A*C + 10*(A*D + B*C) + 100*A*C

I'm a physics student
User avatar #5 to #1 - lemoron (09/27/2013) [-]
yay physics
#6 to #1 - PhantomDog (09/27/2013) [-]
Well only one problem. The first part of it is supposed to be B*D, not A*C. However, besides that, it is a nice proof
#20 to #1 - elcapiltan (09/27/2013) [-]
Almost right, first term in the last line should be B*D

I'm Japanese and thought it was totally normal, what's so surprising?   
also this is how we confess love

in murrica we put the numbers over one another.
User avatar #63 - mereu (09/27/2013) [-]
I've been trying to understand this for the past 30 minutes and it still makes my head dizzy. I still find it easier the conventional way. Or maybe i'm just stupid
#64 to #63 - Hybricide (09/27/2013) [-]
I don't understand this method and I had difficulty learning the way most kids are taught in the US.   
   
My brain just can't comprehend.

Count where the lines cross over.

The first number is the top left corner. The 2nd number is the top right and bottom left. the third number is the bottom right.

the circles look like a % sign.

The abacus system is really amazing for speedy calculations. If you have the time, I suggest searching for Mental Calculation Record, and watch the world record.
The abacus is a tool, that allows a person to calculate a number without ever doing any math. Calculation becomes a mechanical feat, and the japanese students are then taught to visualize the abacus in their heads. They simply remember the position of the beads, and once all numbers have been factored in, they read what it says
Naturally this has it's shortcomings. As calculation isn't mathematical, once the numbers or operations start to get more abstract, they tend to fall behind students, who've done calculation in the traditional way; if they can't apply the abacus, they don't have as much training.

Ofc, they're japanese so they naturally get training in abstract calculating ;-)

Yeah... I always just did math in my head. **** showing your work and **** the system!

A friend of mine showed me box multiplication the other day and it works really well for me. I wish they would have taught us box or lattice method growing up instead of long multiplication. It feels a lot more comfortable for me to do it with the box method.

How I count 13*12
= 10*12+3*12=120+36=156

Something more complex like 75*48 would be
=75*50-75*2=5*750-150=2*750+2*750+750-150=1500+1500+600=3600

Our school was taught this.

I never used it though, Traditional masterrace
User avatar #8 to #7 - psykobear ONLINE (09/27/2013) [-]
Yep, same here.
Lattice method.
User avatar #73 - lovepain (09/27/2013) [-]
anyone willing to teach me this system or send a link where i can find it?

I watched this earlier and it made a lot of sense. I couldn't figure it out at first either.
User avatar #72 - ultimatebadass (09/27/2013) [-]
I feel like it would take a long time to get used to this, once you did it would be easier but as of now it seems a lot more confusing
User avatar #76 to #67 - soupkittenagain (09/28/2013) [-]
Or add 2 zeros to 15 and 1 zero to 38. Then it'll be 1500+380+24=1904
User avatar #65 - Kainim (09/27/2013) [-]
this is actually the Mayan method
User avatar #39 - bitchplzzz (09/27/2013) [-]
now i feel stupid

Our math teacher learned us this some weeks ago ( and im from Sweden)
Im still using it and it's amazing!
User avatar #40 to #37 - aabbccddeeffgghhii (09/27/2013) [-]
I almost corrected your sentence in a douchebag way... Then i saw the Swedish part... You get of this time...
#42 to #40 - AnusViolator (09/27/2013) [-]
....... So what's your excuse?
User avatar #46 to #42 - aabbccddeeffgghhii (09/27/2013) [-]
Hes Swedish! He didn't even notice! Also, i forgot an f, he said "My teacher learned me." SLIGHTLY different if you ask me.
#47 to #46 - AnusViolator (09/27/2013) [-]
I'm more referencing you. "You get of this time". Just thought it was kind of funny, commenting on his typing while making a mistake.
User avatar #49 to #47 - aabbccddeeffgghhii (09/27/2013) [-]
Yeah but i just forgot an F... Thats an honest mistake. Same as Your instead of You're.
#50 to #49 - AnusViolator (09/27/2013) [-]
I think you're still failing to see the irony of it.
User avatar #52 to #50 - aabbccddeeffgghhii (09/27/2013) [-]
I get the irony, its just not that important.
#53 to #52 - AnusViolator (09/27/2013) [-]
"I'm wrong so it doesn't matter"
User avatar #55 to #53 - aabbccddeeffgghhii (09/27/2013) [-]
I said the irony didn't matter, I said nothing about my mistake.
User avatar #41 to #40 - xgreenmaidenx (09/27/2013) [-]
Thank you for sparing me.
User avatar #36 - tigleytummy (09/27/2013) [-]
I wasn't taught any of this fancy **** .
Thanks primary school.
