Oh my god~~~Do all the Westerners do math in this way??

[Darkhellokitty1]

No we don't I don't ever under stand this it is confusing we just simply do Ix2=2 or something like that

[DanielLaneDC]

That's like diagonal matrices. Since regular multiplication is identical to single row or column matrix multiplication, you find this significance.

Maths is universal. Methods are different, but if you look in the right places you'll see the absolute truths.

interesting trick. never seen it

[lastdon85]

i think this is supposed to be a way for people to do math that have trouble with numbers by changeing it into a spacial representation of the numbers

a shape that expresses the problem but no i use a calculator ALWAYS

[heylookitsnana]

This is really cool! I'm in the US and I'd probably cluster, do it the 'normal' way, guesstimate, grab a calculator, groan, or check out Wolframalpha. Then again, by the time one is in Algebra, being able to do multiplication like that is no longer the point and everybody uses a graphing calculator.

[jriffiths]

no. we probably do the same thing you do.

[ableartistasylum]

cool but would get quite cluttered when doing 987 X 898. Don't you think?

[gr8alias]

21 x 13 = uuummmm lets see.... 20, 13's + 1, 13 = 260 + 13 = 273 or Um 10, 21's + 3, 21's = 210 + 63 = 273 It's called the NEA seems they come up with aaall kinds of BS ways to do things .... now now - not all are bad, and if a kid finds a way to get the correct answer EVERY TIME - then let them use it. But it seems to me, that this vid demonstrates a Krappy way to do math! from the US- have a GREAT day!

[LegendSaber]

I'm from the United States and I've never seen this kind of math before. >_>

Seems kind of neat. Though it looks like you need a lot of space, and it takes longer than regular long multiplication. Though ultimately I think I'll stick with my calculator. ^^

this video orifinated in singapore. harly western!

[DoubtingFaithcom]

Kind of cool but a bit of a pain if your in the hundreds... Who assumes that Westerners do Math this way? Many people have a hard enough time multiply or counting change. Could you imagine if people had to draw lines when ever they multiply something? Some people can't even count change, how would they ever count intersecting lines.

[mcrxtbp]

we use lattice o.O

[ZuhairahR]

ummm us westerners use something called a CALCULATOR

[omingud]

HAHAHAHAHA xD

[ShadowShifter64]

ha ha, we are pretty lazy...

[DrewFace507943]

I believe this is Indian notation is it not?

[ragstoriches919]

does it only work for numbers with 1, 2, and 3?

[geesoz]

this is the biggest crap of a method i have ever seen!

if you don't have a calculator, learn the standart algorithm.

[NAQW]

I don't use this meth!

[zhuweili]

I use a calculator hurrrrrrr. I learned that method when I was in grade 3. The method really helped when you weren't allowed to use the calculator
