Chinese Multiplication

[cherry1234567]

this is lattice mltiplication

[AQWTmyster7]

OH MY GOD, ive been putting the unit into the hundreth column all this time :S Thanks for the help :)

[senditon1993]

i dont think it's right way. Try 1938x246 and then calculate with your caculator

[MattBlytheTheOne]

@senditon1993 hi, I tried it I got '476748' first time :) took me about 1/2 a minute. Are you understanding the process? Perhaps you made a simple mistake in your arithmetic?

[JessjiTV]

@senditon1993 Huh... Get it right! You've done it so wrong. I've just worked it out and it came to exactly what it said on my calulater. Maybe you ought to watch it again, and get it right this time!

[MattBlytheTheOne]

@JessjiTV Huh? Which bit do you think I got wrong?? lol

[MattBlytheTheOne]

@WCWinxClub101 OK I get it thanks :P lol

[MattBlytheTheOne]

@WCWinxClub101 MISPLLS? where? haha SHOW ME

[dylanlovell]

Nice 1 for this it really helped

[mystyka13]

OMG I LEARNED THIS IN 3RD GRADE AND FORGOT AND HAVE BEEN LOOKING ALL OVER TO FIND IT THANK YOU!!!!!!! :)

[hulkhogan100]

i learnt this in year 7 o.O

[yuirrr]

It took you too much time...

Making the multiplication in the ocidental way was faster to me.

[MattBlytheTheOne]

@yuirrr when you learn it is really easy doesn't take any longer than the traditional method but is simpler to add up :) each to their own you use whatever you are comfortable with, I made a video about it that's all :P

[kendrysa]

@yuirrr I did in 10 sconds

[MattBlytheTheOne]

@kendrysa pretty cool :P

[TheWillieee]

Very nice, but why taking the time to draw those grids?

My mom taught me just put the under each other and then do multiply with each other, kinda like what you did. That's way faster :o

[marquisofAngels]

wow.....say...dis is awesum!!!!u jst saved me loads n loads of time n effort...luv u!!

[MattBlytheTheOne]

@marquisofAngels awe-sum haha thank you :D

[fizzixizpro]

Um this is called Lattice Multiplication. I learned it in 4th grade... :D

[keltow]

Took you 5:38 to finish, I could've gotten a calculator in that time :P

Joking,, Very cool 'trick'

[MattBlytheTheOne]

@keltow we used to this at college in exams where no calculator was allowed! Thanks, not a trick just a way of laying out the math that makes it easy.... :)

[yzzl91]

the fastest way is use calculator

[MattBlytheTheOne]

@yzzl91 not if you don't have a calculator !

[MejJalTok]

My teacher said this was lattice multplication, and he said that we should go from right ot left. It's the fastest way to add numbers (cuz that's how we originally are taught to do them --- from right to left). and we add numbers according to the way the lines flow in form of a diagonal rectangle so that the numbers add up from right to left and finally from bottom to top. You did it just from the right then suddenly from the top to bottom. weird and confusing.

[MattBlytheTheOne]

@MejJalTok this IS the lattice method! It doesn't matter which way you fill the grid ie. left to right, top to bottom, I guess it depends which hemisphere your brain is at :P

[gjpshallow]

this is really wowwww

[MattBlytheTheOne]

@gjpshallow thank you for sharing :)

[gjpshallow]

simply wow



[CiviliTary]

Got lost on the diagonal addition part. Forget it the old fashion way is easier and quicker

[MattBlytheTheOne]

@CiviliTary says more about you than about the math !

[CiviliTary]

@MattBlytheTheOne

I'm 25 I can add. I didn't see every step used like how you was carrying the one and all.

I dont care to watch over and over because I prefer the regular way.

[MattBlytheTheOne]

@CiviliTary OK basically you multiply each number with its coresponding number in the grid and write the result in its box. Add the integers in the boxes DIAGONALLY if the result is greater than ten write the larger number under the next set of diagonal and add as before. Once you sus it becomes really easy and you NEVER need a calculator even for large numbers. In essence it is the same basic math as the regular way.

[Achtohpuss]

... This is the lattice method, I don't know if it's Chinese or anything, but they teach you this stuff in like second grade.

[MattBlytheTheOne]

@Achtohpuss Yeah it originated in India I believe :)

[FuglsangProductions]

You could also use a calculator

[MattBlytheTheOne]

@FuglsangProductions  not in an exam without calculators !

[weluvchees3]

wow, im gonna use it at school. thanks a lot! lol :)

[bgurtz]

i don't understand!

[MattBlytheTheOne]

@bgurtz @bgurtz You multiply each nuumber with its corresponding number and write the result in the box., then add the numbers in the boxes diagonally to get your result..... try watching the video again! :)

[bananian]

is this really the chinese method? Isn't this the TERC lattice method?

[MattBlytheTheOne]

@bananian yes that is correct, Lattice method from India!

[9412401234567890]

fking copy cat...i made that up...wat's yo name i was the one who made this up

[MattBlytheTheOne]

@9412401234567890 you don't have a name you have a number !!!!

[MattBlytheTheOne]

@DizzyDerwish OK DIZZY !

[MattBlytheTheOne]

@DizzyDerwish Your comments and your self styled judgments have been duly IGNORED thank you!

[TheMrdominator1997]

Thankyou this helped as ive got a non calculator maths exam tomorow!

[MattBlytheTheOne]

@TheMrdominator1997 Cool :) hope it went well for you.

[tomvercruysse]

LOL song is by Moby, oh yeah one of the many songs by moby?

[MattBlytheTheOne]

@tomvercruysse LOL what's up with Moby?

[MattBlytheTheOne]

@shinyb0y 6 x 7 = 42 (the first column of boxes) each number is multiplied and written in its corrsponding box, the boxes are then added diagonally to give you the answer. Unless you are misunderstanding the method in the video you are correct 7x5 = 35 (the third colum). Later on in the video I made a mistake 6x7=43 LOL thanks for commenting PEACE !

[ryders3000]

@shinyb0y its 7x6 and not 7x5 ;-)

[MattBlytheTheOne]

@shinyb0y lol thanks :P

[anisuthideyakoindu]

what s this nice music?

[MattBlytheTheOne]

@anisuthideyakoindu hi its by Moby :) thanks

[dextermanus]

Hahaha never realised a Chinese smiley actually has Chinese eyes!

[MattBlytheTheOne]

@dextermanus ¬ _ +

[TheBasicStamp]

Exact same as normal multiplication, you have the same amount of steps. It takes longer to do this because you are required to create a grid. For those of you who think that this is a faster way to multiply without a calculator than normal multiplication, YOU ARE WRONG! This way can be a little easier because it is more visual, but it takes up more space and is slower!

[MattBlytheTheOne]

@TheBasicStamp whatdayoumean "YOU ARE WRONG!?" Wrong about what? I never claimed it was faster... doh!

[TheBasicStamp]

@MattBlytheTheOne I was directed to people who made comments about it being faster, not you. I'm sorry if you think that it was directed to you.

[MattBlytheTheOne]

@TheBasicStamp Hey! No worries :) This is just a simple way I learned in college. Use whatever way you are comfortable with, it's all good :P

[MattBlytheTheOne]

@TheCovboy123 ha !

[Krames92]

Where did 43 come from? 

[MattBlytheTheOne]

@Krames92 lol exactly ! Well spotted...

[MattBlytheTheOne]

@jacksawild bit of a drastic leap don't you think?

[KrayzeeLife]

we do this in my skool, it's called lattuce

[MattBlytheTheOne]

@KrayzeeLife yes it is called "lattice" :)

[KagameKatz]

I learned this in 5th grade. I don't use it often though.

[xcommunicate]

Because Chinese invented multiplication

[DizzyDerwish]

"Chinese?"

What's so Chinese about this?

The University of Chicago School Mathematics Project is a world-reknowned program and teaches this algorithm; they would be bound to cite the cultural source, ie. Chinese, but it is known simply as the lattice method of multiplication.

I have never heard it originating with any specific cultural group.

Take off the mystique, okay?

[MattBlytheTheOne]

@DizzyDerwish The lattice method originated in India. We were taught in high school it was called the Chinese Multiplication method. Who cares what your school teaches they don't own it, it's just an idea. Dizzy indeed.

[DizzyDerwish]

@MattBlytheTheOne

'Dizzy indeed'

Name-calling? But be fair!

SuzeyCue (below) told you this method's widely-accepted name three months ago, and you only seemed to chuckle then.

Now drop the mystique.

[MattBlytheTheOne]

@DizzyDerwish I Like Mystique.

[GoldPuffle]

i learned this in 5th grade :D

[Ddrhl]

No one seemed to notice you used the word "equation" for something which is an "expression." Makes me sad.

To your critics who say one method is "faster" than another...that's a useless comment. Faster for whom? Why is "faster" your criterion? Which results in fewer errors? Which method leads to true understanding of multiplication?

[MattBlytheTheOne]

@Ddrhl hi great comment, personally I found this way easier to remember :)

[SuzeyCue]

This is also called LATTICE MULTIPLICATION. I have never heard it callled "Chinese Multiplication." The way I learned it - when adding the digits diagonally - you keep the sum under the diagonal boxes. I think this is a good video except when you add the digits (because you aren't keeping the sums under the diagonals - it appears a bit confusing.)

[MattBlytheTheOne]

@SuzeyCue haha thanks yeah it got a bit out of shape there :)

[stetco86]

the one with the lines is easyer

[LETXEQUALS]

THIS LOOKS LIKE TAKE LONGER THAN THE OLD WAY, OR THIS IS A BAD EXAMPLE ?

[MattBlytheTheOne]

@LETXEQUALS that is a good example of a bad comment LOL

[bharatnaruka]

No offense to your way of multiplying, but this is no different and definitely not faster than the regular one.. because the basics are same and you spend extra time in drawing those boxes

[MattBlytheTheOne]

@bharatnaruka Maybe but this just simplifies the process in my mind. The box drawing time is insignificant. None taken thanks for commenting :)

[1353233]

this one is faster than the japanese 'grid' system

cool!

[drag0nblight]

Napier's Bones works the same way. Simple and reliable. Do you have something for division?

[MattBlytheTheOne]

@drag0nblight I don't do you? I never liked long division !!

[CalyxAsgard]

I can see why asians like the Chinese and Japanese have the rep as maths geniuses with logic puzzles like these to help sharpen the mind.

[jenna756]

This is what we do at my school!!! im not chinease im american LOL

[MattBlytheTheOne]

@jenna756 cool i'm english, I learned this at college! :)

[jenna756]

@MattBlytheTheOne you learned this at college? i learned this when i was in the 5th grade we have to use it at my school. im going to the 6th grade, and we HAVE to do it... but it is easier. lol

[MattBlytheTheOne]

@jenna756 lol your profile says 25! Yes it is easy and handy if you do not have a calculator... wish I had learned it in school :)

[jenna756]

@MattBlytheTheOne LOL i know it does... but it is just to get on youtube. XD you do? i wished i hadnt... LOL

[MattBlytheTheOne]

@jenna756 I just needed an excuse to play with my camera :) I'm still experimenting with youtube lol have a nice day and subscribe if you like, Matt xx

[rproono]

thank you.,



[MattBlytheTheOne]

@rproono aww thank you for watching :)

[aznboy3213]

the reason we learn complicated stuff is because there is a lot of people and it would be too easy if everyone pass all the test so they make it way harder but anyway im lucky since i live in the Canada :)

[MattBlytheTheOne]

@aznboy3213 I think the eduction system sets a standard, a goal for people to work towards... we all have different Gifts and levels of learning, I don't think it is indicative of failure if you are not good at maths for example. It might just mean you are Gifted in other areas :)

[MattBlytheTheOne]

@aznboy3213 I spent years reaching quite a high level of mathematical understanding and I use hardly any of it in the business of life ! Just goes to show...

[wuiyang]

i from malaysia, i'm chinese,i learn this, but i thing this was so hard to calculator

[MattBlytheTheOne]

@wuiyang lol this is the easy way !

[klowranc]

this is completely retarded... how are the Chinese taking our engineering jobs when they're being taught this crap?

[MattBlytheTheOne]

@klowranc because they are being taught this crap at about the age of two years!! that's why.

[runepoosux]

Yeah, it's easy. But I don't think it's Chinese. It's called "Lattice"

[moreirajesse]

very cool

Thank you for send this video

[melymelz99]

I do not think this is " Chinese Multiplication ". This mathematical method is now known as " Lattice " ( lat- iss )

[ltq19900310]

Chinese Multiplication ? As a Chinese , i never learned to calculate in that way , but i'm sure i can do those multiplications in regular way faster than that

[MattBlytheTheOne]

@ltq19900310 Some people are saying it is indeed the the "lattice method" originating in India, please forgive my english!

[williamlovejr]

thanks for sharing! however you went too fast! could you go slower next time please? thanx

[MattBlytheTheOne]

@williamlovejr no problem William :) thanks!

[MrPacman187]

its cool but na im good i dont like anything about the way i was taught

[MattBlytheTheOne]

@MrPacman187 first thing I learned at college was "HOW" to learn! Then to be a good student...

[MrPacman187]

@MattBlytheTheOne thats a good piece of advice

[MattBlytheTheOne]

@MrPacman187 ....or at least "do your best" :)

[MattBlytheTheOne]

@NinjaXSong thats amazing thanks for sharing :)

[Godret1]

Китайцы воруют ВСЁ. Даже идеи и методы!

[MattBlytheTheOne]

@Godret1 lol I think this originated India and is called the lattice method !

[Godret1]

@MattBlytheTheOne Я точно не знаю. Но вроде первые изобрели этот метод в Южной Америки, ещё до рождества Христова. Сами они догадались, или им помогли инопланетяне никто точно не знает.

[MattBlytheTheOne]

@Godret1 haha I love google translator :)

[Godret1]

@MattBlytheTheOne :)) Да он очень помогает общаться.

[NinjaXSong]

@Godret1 lol...I'm Chinese-I came to US when I was 5 yrs old...but, I remember in preschool (age 2 to 3), we learned stuff like 143+234324 (addition like that), and when I entered an american school, the kindergarden math was an insult to my intelligence...the class had trouble keeping up with stuff like 6+5!

[jaki54321]

what grade do they teach this in china?

[MattBlytheTheOne]

@jaki54321 I have no idea but I bet it is younger than here in the UK !

[MattBlytheTheOne]

@jaki54321 I don't know that they do teach this in China!

[GOUBO1994]

or just use a calculator?

[MattBlytheTheOne]

@GOUBO1994 true but some exams do not allow the use of calculators :)

[danielroshanmoniri]

In my opinion i that you explained this method really good. : )

[MattBlytheTheOne]

@danielroshanmoniri thank you daniel :)

[invis648]

That marker looks like it gives off toxic fumes.

[MattBlytheTheOne]

@invis648 it's not that difficult !

[invis648]

@MattBlytheTheOne I know, the multiplication method you're using is very simple! I'm not talking about that at all, I'm just saying that blue marker that you're using looks like it's the kind that gives off toxic fumes -- the kind you shouldn't breathe around too long :P

[MattBlytheTheOne]

@invis648 well it does smell kind of nice ;-) lool

[MattBlytheTheOne]

it's actually the same process but laid out a bit different! The other way is quicker for YOU because you are used to using it...

[holdenwi]

i agree with nadjusca. even though it is the same process the part of drawing the grid takes longer. but this is very very interesting. thanks for uploading

[MattBlytheTheOne]

draw faster ;)

[XXXGurlRockerXXX]

i dont really think its chinese.. we learned this at school and they called it lattice my teachers didnt mention it was from china

[MattBlytheTheOne]

I think it originated in India

[MattBlytheTheOne]

@XXXGurlRockerXXX yes the lattice method form India you are correct good student :)

[lucile1010]

whoa thx for dis!!

i tried to learn d other way bt they didnt show hw to do it whn thr's zero..

dis wuld really help in non-cal paper i think.

thanks lot.

x

[MattBlytheTheOne]

hey :) thanx

[lucile1010]

=DD

just curious, do they have a similar way to do division??

xDD

[MattBlytheTheOne]

don't know, I hope so I always struggled with long division! :)

[wangxiamei]

It's... just like normal multiplication. Just in a different format. But it's the same :o

[MattBlytheTheOne]

of course, it would have to be to get the same result :)

[TheSomeone717]

this is a really easy way to do math like that and its not chinese btw

[geminisch]

its more complicated than the criss-cross method.

[localbandss]

i rather use a calculator

[MattBlytheTheOne]

O_K

[boyblue1171]

Chinese? No it's not!

Simple? No, it's not!

If you know how to multiply two one-digit numbers, why not simply multiply the whole thing?

[MattBlytheTheOne]

Well the simple answer is : because i like it this way! doh :)

[Flow60200]

It's not chinese!!

It's the methode "per gelosia" used by the arabic

[MattBlytheTheOne]

hi, it seems it is called different names in different parts of the world... I never heard it called that before, thanks :)

[Flow60200]

thanks for the precisions

[Gibshift]

Wow alot easier that the Mayan way to calculate, i was stuck with 653x 845 in mayan way, but got it right away in this method. Thank You

[adobogirl]

great technique, but not digging the drawing or the "ah so"

[MattBlytheTheOne]

OK digging? Is that a western expression?

[adobogirl]

let me clarify. I really enjoyed the techinique but not the "chinese drawing" or the "ah so" comments which are just old racial charicatures being retold by you. thanks.

[MattBlytheTheOne]

What Chinese drawing? And what EXACTLY does "ah so" mean to you? Thay are your judgments... Ah so is simply a moment of realisation recognised in many different countries and communities... strike two! ;)

[MattBlytheTheOne]

OK thanks but if you think that is radical... don't watch my other videos! lol

[Oathblivion]

Hm, for a visual person like myself, this might be a better solution for multiplying in my head. Thanks for the upload.

[hofiraz]

haha, "和" means sum

[MattBlytheTheOne]

cool :) thanks

[hofiraz]

your welcome, and thanks for the solution. :]

[camirrakiu]

Oh soooo great, man. Thank u for share.

maybe tonight i'll make a chilean version of ur video, is so great, really.

Thanks 'n peace too.

Camirrakiu++

[MattBlytheTheOne]

thank you :) love and peace

[MattBlytheTheOne]

ok thanks I deleted your comment by mistake :)

[AmidaKun]

jajaj pucha compare

es verda qe dicen qe los chilenos

copiamos las cosas bacanes de los extranjeros xD

[MattBlytheTheOne]

in English please , do I look like an alien?

[xiaolintraditional90]

cool. but won't this take longer than to multiply it the american way where you multiply from right to left and then add up the numbers?

[MattBlytheTheOne]

hi, Possibly! ...it depends what you are comfortable with...

[tyler1820]

Isn't that called Latis multiplication...

[MattBlytheTheOne]

yes! ...and chinese multiplication!

[panuelita]

The slits-for-eyes and "ah so" were only slightly patronizing. Awes.

[MattBlytheTheOne]

me...? patronising...? ....NEVER!!

[AnimeladyOMG]

This is the Lattis multiplicatoin method. It's nothing special, I learned this in grade school and it's my main form of multiplication. I'm not Chinese, btw.

[MattBlytheTheOne]

thanks for commenting!
