Math trick. Use box to solve math problem

[MrEricbellamy]

now if you can only show me how to take a toy out of it's plastic covering then we will be good....

[TheNmklop]

i learned this in third grade its one of the three standered multipulcation techniques its called lattice

[DLLAMAS77]

omg i always saw a girl right across from me do that

[gtamikesvideos]

Thanks man.

To others try this as a test :)

222 X 22

[erc1234g]

great...give us more videos showing ...division, comlex addition, and fractions.

[lnventlve]

worst thing about this is assuming any one will ever manually calculate something instead of using a calculator/computer, which is standard anywhere you have math needs which meet this problem.

[JoshMr07]

very clever... is there a way like this to solve a Fourier transforms?

[11111vineet]

lattice ever heard of that

[ThomasBHofSoCal]

HORRIBLE!!! Okay kiddies, let's take something and complicate it so it'll take much longer...

[TheShyanblue]

thats awesome!

[Wisdombluetooth]

Time consuming more than the standard way of multiplying

[NScott45]

I don't see how that's any different than the standard method... it's just written differently...

[techdecknoob100]

The proper name for this kind of mathamatics method is called *Latice*

[cbman1000]

@techdecknoob100 yep your right latice multiplacation learned it in third grade

[techdecknoob100]

@cbman1000 same i learned it in 3rd grade.

[MsKikira]

u just made my life easier, i could kiss u ^^ lol (just kidding) thanks for this vid

[06pag]

This isn't a trick, it's normal multiplication with lines drawn in between to make it look pretty.

[pelitomojao]

how did you get the 2 and the 8 on the left side of the box?

[markgriz]

Seriously 1:30 to do this? Took me 10 seconds the normal way.

Only reason for this "technique" is to sell new curriculum to clueless educators.

[rajforeverloveu]

not applicable in big numbers

[SIRA063]

whats the name of the piano piece?

[bluehawk117]

i never used this and when i moved to ohio, this is what they did. I still don't understand why they just don't do it the easy way.

[RotundRiceRockets]

Dude I learned that in third grade it's called lattice multiplication. -_-

[All6usto]

What If The SUM of the elements in line ends up having two digits???

[jesriljr]

@All6usto use a calculator

[averygrandma]

@All6usto You take the tens digit from that number and carry it over

[baardi2]

o.O awesum

[beekrazyleg]

0o0oo nice..

[clevehillflyer]

Not sure how this is any easier than normal multiplication at all! As a math teacher I am saddened that elementary and middle school teachers teach crap like this to our students. It is no wonder that when they get to high school their number sense and mathematical skills are so low. Do you think they teach this to the children in China??

[sexifencer]

@clevehillflyer As a teacher, especially a math teacher, you should always be happy to have multiple methods to present to your students. This method is not any easier speed-wise, but some students have trouble with the "traditional" method and so if you present them multiple ways of doing the same problem, one of them will click and bam you just had a light-bulb moment. Not every student learns the exact same way. Use some critical thinking skills before you put a method down.

[zer0vital]

This 'trick' is much more complex than simply doing the problem normally, it takes much, much longer, is completely impractical in any real-life or testing scenario, and actually reduces the person's comprehension of what is happening. I would never teach this method to my children, and it should not be relied upon by anyone.

[Bracia12345]

@zer0vital yes

we had to learn this method at school

[TwoTekah]

@zer0vital but then again that is what half of school is :P impractical and non applicable to real life. people only retain about 20% of their schooling.

[RubixKidCube]

dude can u show us ho 2 freken do it?!

[SanZangFashi2]

THIS IS CALLED LATTICE I'VE BEEN LEARN IT IN 4TH GRADE AND I THINK ITS THE EASIEST WAY TO SOLVE A MATH MULTIPLICATION PROBLEM O.o

[tazzielala]

AMAZING!! Thank u 4 this! Now i can teach my kids an easier way 2 do multiplication!! Mahalo nui loa plenty!!

[rubberbandman9999]

@BillyGatesHabbo ya i knew it in late 4th grade.

[macmania1000]

ok dont use this,most of the time you get the wrong answer,my math teacher said latis

[pathmatharani]

hi, i believe that this is one of the best ways to do calculations!!! well done

[jennie5532]

is this latis?

[rneville101]

Might not be the fastest way to do it but it sure is elegant.

[Dsupreme1]

this is the stupidest fucking method possible

[KrisannCarminaCaoile]

Lattice Method!!!!!!!!

[PokemonMASTER008]

handy when comes to 3 digit time 2 digit numbers,i tried one and it worked!

[IAmSoTight1]

too bad this is the longest way possible.

[Jamarama91]

finalllllly a video on youtube that makes sense

[Niko653]

@Jamarama91 Most of them do, you're just stupid :)

[Jamarama91]

@Niko653 nahhh you just suck dick :]]]]

[linuszero]

btw it's called Gelosia .

[Entertainmentwf]

All this is, is the natural algorithm for multiplication just drawn differently ....

[virendra81991]

hey i think this one is not a trick , this one is a good way to time pass.......

[GuitarHeroInTraining]

What if the number you add up goes over 10? :P

[Meraj99]

@GuitarHeroInTraining carry the 1 to the previous digit

[Skaterboy692]

It's called lattice.

[MaxaTheeGreat]

I use lattice all the time. Not new to me.

[ellisbradyuk]

this is called latis multiplication or as others say chines multiplication

[belyemen]

735 x 72 ... can anyone try it ..with this way?

[belyemen]

@belyemen it is ok ,, that's a nice way .. thanks

[averygrandma]

@belyemen I tried and got 52,920. Then, I did the normal way and got the same answer.

[RiceBoiKev]

only works with 3 digits multiplied by 2digit

[e1cks]

@RiceBoiKev lol

it works with any number you just need a bigger grid

[omfgjeremy0]

He should have added the numbers from right to left. For double digit sums, carry the tens digit in to the next left most box, and write down the ones digit. Then it should work.

[kinterodavid12]

standard is faster lol

[3719athemallkanpur]

nice method, I learnt

[Hypergirl74536]

I did this in 4th grade but i forgot it :p

[Vnask00s]

4567 * 258 = 1178286

with trick

= 8378336

it 's wrong

[TheyDontSee]

yeha I put 4567 on top and 258 on the side and go (in order of the video) the following numbers:

0,11,6,16,11,18,6

...I'd like to see a video on how to use this method for this equation...because when you add up diagonally you get double digit numbers... what do you do with double digit numbers?

[100anglegirl]

smart

[weethisfun12]

this is latice so gay

[LittleHeroine]

it works ;D

[karenher206]

Wow!! (*sarcastically*)

This is Latice! I learned it in 4th grade!

[Goku32176]

i learned this in 3rd grade

btw itscall latice

[thefinalb0ss]

I...prefer standard multiplication o.o?

[karenher206]

@thefinalb0ss: yeah! it's much more easier(wells for me)

and there's less steps to it!

[averygrandma]

@karenher206 You take more time drawing boxes then multiplying the numbers and adding them up

[GuoSlice]

nevermind i got it

you carry that shit

[GuoSlice]

yo

this doesnt work

i tried it with 1764 x 4267

what happens when you add up the diagonals and they give you a 2 digit number? do you carry it or no?

[Agnieszka214]

@GuoSlice yes u do carry it. When you have a 2 digit number, you carry it to the next diagonal box or if it's the last box, you don't carry it.

[lakers2galaxy1]

how will it work if you go onto using it with two 3-digit numbers like 104 x 401? will it work on that as well?

[DrewAWeeks]

That is fantastic

[Blasterider45]

latice sorry

[Blasterider45]

ita called the latic method

[andrea771991]

I learned this in 3rd Grade in Switzerland...I think it's pretty cool :)

[jaeshim1]

It takes longer

[SlaeR100]

trying 733x33=?? This method not helped

[Usiek1992]

Of course helped too. I did. When you have 3x3 you write in first check 0, then 9. And then you do it like before ;)

[yurishosan]

works fine to my...you just add the tens to the bigger number...like every ather math trick...you should had figered that out...

[ChangeThePicture]

that is so easy i learned that in 3ed grade and im in college right now

[Bimallove]

This is called lattice multiplication.

[PreZZDee]

Omg

I so remember learning this in class

Like in third grade.

Totally forgot until now. ^o^

[jkang8D]

song

[andrei172007]

this proves that romanian education is stupid. we never learn neat stuff like this.

[vondelmolen]

just stuff you do with matrixes there are planty of them.

it's handy.

what gr8 are you in?

cuz i saw that in my last year of highschool.

[andrei172007]

i'm not from America. i'm from eastern Europe, from Romania. i just finished highschool, and we never did anything like this.

[vondelmolen]

ow i belgium we did.

[halobed2]

Balkand and Romania have calculators so.. lol

[victorinopikmin]

i think you would have done it faster if you used the standard algorythm instead

[godfarther12]

maby^^

[loxo985]

cool

[takurouzamaki]

dude i lerned that in like 3rd grade

[superhoyuelos]

why dont you just use a calculator

[arjan22322]

@superhoyuelos

[Just4Th3Lulz]

@superhoyuelos because it's hard to do math with a calculator if one hand is rubbing your dick and the other writing the problem/answer.

[dillon781994]

@superhoyuelos because we're all not retards

[lilsnoopy2323]

@superhoyuelos in real life and you don`t have a calculator what yea gonna do when you don`t know how to do problems cuz life deals with numbers all the time so what if the battery to calcultor runs out? or something histercal happens to it whatcha gonna do then? xD

[crazyboy123252]

i lernd it in 4th

[Goku32176]

its called latice

[gio2475]

When I was little, I thought that this way was easier, until I realized that I could do it the naormal way without wasting time drawing boxes.

[jesriljr]

@gio2475 my school never even taught me the normal way. so if i dont have a calculator, i gotta draw boxes...

[06pag]

@jesriljr It's easy, just multiply the left number by every digit of the right number, then add the right most digit times left number, second digit on the right times left number times ten, third digit on the right times left number times hundred, etc. This "trick" does exactly that, but draws boxes in between for some reason.

[rwang83]

it's not much different than conventional way, i guess that whole carrying over bit could mess you up. this is just letting you track the carry over digit better.

[SoundsGayProductions]

i was taught that a while ago and its helped me alot in school...in like 4th grade when i didnt want to do much work

[ICHBINPERFEKTION]

nice ^^

[jcbluebird]

he added them up the wrong way lol

simple maths says u add from the lowest numbers first ;)

[Antonmorrisisalegend]

added? u got that wrong mate didnt you?

[lolpinkhair]

He added them up right, but he did it backwards because if he had to carry over a 1 (number in the boxes added up over 10) then he would have had to go back.

[MangoesForSale]

-.- isnt this called the grid method?

[thepapergunmaster]

you are supposed to add them up the other way (start from the other direction) in case any answers add up to more than 10 so you would have to carry on one

[IchxBins]

Can someone tell me the name of the tune ?

Thanks =)

[Youradumbassbarnes]

Called the lattice method its the easiest way for kids to solve a long math problem

[poptheman1]

we do this in school

[bizinessfirst]

I think it would be nice to know how this process works when you have digits adding up to more than ten in the diagonal lines. I tried 495 x 38 and could not get it with this method. it's good to know both ways because you never know what the ending diagonal numbers will add up to.

[poisenman6]

woudn't it be easier to just use a calculator?

[wiirocksgh]

It's called lattice

[kemestri]

smart.

[gmayer66]

It looks like a very nice variation on the way of using a device known as "Napier Bones". I'll use it. Thanks!

[dyjorge]

Euler was the Maathematician who developed this way of multiplying 2 numbers

[nkitty78]

neverr do math in sharpie.

plus they look like punnet squares. O.o

[Earthbound64]

well...it depends on how fast you use such tricks cause the normal method can be used very fast and i think tihis one has no advantages against the classic method ;)

[coolmathgal]

This is a great method, and I teach it. What matters is that it is easier! It would be good to show what happens if the digits along diagonal add up to 10 or more. I'll probably make a video explaining it. Better for students to understand as opposed to worry about space on paper. Great job!

[sasuke000naruto]

Yeah this is the one I used back in school but always used up to much space on the paper lol

[RYANBRADLEYCOMPANY]

This method is called latice pronounce as LA-TIS

[xxCash42xx]

haha here in america we like to call the lattice and it is agains the law for teachers to teach it now! cause is such a waste of time

[OscarLiu24]

u call this a trick?? it's a wasting of ink+paper+energy+time.... even the older way is faster...

[FabFubar]

wow, i was taught another way

this way makes it look more fun though :D

[lilmemissu]

um?

[mokoraz]

tre bien

[traunkin]

Ahh yes, Lattice. Made math so much easier in 5th Grade.

[girlyangelcute]

our teacher told this to us when i was 5th grade,...

[JoeDeZ52]

me 2

[KurdstanPlanetarium]

Briliant...thanks

[rayven123456789]

yeah that was called LATTICE METHOD

[Stickguy7]

its actually called lattice

[coolcollio]

yea

[sk8zero123]

they dont let people use this method in my school they say it dosent show number value or some bullshit like that

[CinnaminHearts]

this is gay

[lukacod]

Can you send me a Personal Message, I have one question: If u have 2583972 x 92 = 1 12 17 5 21 14 13 12 4 Now, how do to get the final result. The final result is: 237725424 How do you + this numbers to get that resulr. Thank you!

[ratznefumel]

well it goes like this

when you get the number 783 in the diagnoly thing you cont it up like this 7+8+3= 18 so you right down a 8 and the 1 of 10 is ging to the number you solves before

[myownreflection10110]

thanx:)

[wwwKx]

good method and good music 5/5

[bovko1]

hehe! Nice way to multiply big numbers, but calculators are still faster :)

[kkinger55446]

lattice is a easy way to do multpl. if you are in like 4th or 5th grade that is when they teach you it (U.S only I think...) but over all the reg. way is more effective and accurate...

[notejodemosmas]

y si quiero hacer 233 x 33 ?

[wmatts]

it useless, normal metod its more efficent (quicker)

[oto2g0d4u]

wow what a complicated problem, einstein could not of solved it !!!!! :)

[JamesNicdao]

thanks

[mrcomedy454]

rofl my sister just came by and was like "Oh I love the lattice problem" and I had no clue what I was looking at. and my sister is 10.

[avmist159]

i learned that in third grade...it's called lattice multiplication, and in my opinion, it's not very efficient

[Tjkfbi]

ummm okay?

[electriciansmate]

384 x 66 = 25344

[BEAUTIFULmetrah]

Thanks for explaining i tried and it works just with even numbers on the right box.For example i couldn't do with 463x62 soo.Thanks

[electriciansmate]

Loved it, amazing!

[DAMMAMA]

huh?

[BEAUTIFULmetrah]

Why do you guys like to trick us?It doesn't work i tried 384x66 i got 1222144 but is 25344

[JazzMusic79]

Well jan they want to trick you so you watch their video...lol

[BEAUTIFULmetrah]

Yep jan y right.I won't watch this again.Liers lol

[electriciansmate]

It does work. On the outside of the box, left hand side. 1 then 13. Under the box. 22, 14 and 4. So we have 1,13,22,14,4. Now separate: 1,1,3,2,2,1,4,4. 1,1 = 1 + 1 = 2. 3,2 = 3+2 = 5. 2,1 = 2 +1 = 3. Therefore 25344.

[dator36]

uuhh...?

[Agni2222]

noob

[ShinjioRawkz]

omg its kinda fussy...i can't really see it...

[rgracer17]

nice :D

[ParadoxGeek]

Kewl.

[nocalsteve]

That is exactly the same as regular place value multiplication, but a lot more work. I'm not sure how I'm supposed to be impressed with that!

[mkevindelfin]

Thanks... I can do that in 7 secs. but 3 after. Thanks...

[matthew45736]

that would suck if screwed up drAWING THE LINES...LOL

[gulf2345]

do thinks it work with all number

[qwertysow]

have you hear of a new cration called "calculator?"

[FerrilSamal]

gracious. y ve solvd my life long problem.

[xxchocolatexluverxx]

thts called da

lattice method
