math is so easy

[prettyvase]

wow! i never knew this all my life. thanks. Im learning.

[peetraaify]

He is talking like Raj from Big Bang theory.

I cant stop laughing :D

[valeriaerika]

Muito bom. Ficaria melhor se tivesse com tradução.

[TheSvartdemon]

WHAT KIND OF SORCERY IS THIS?

yo im guessing your indian or paki, im paki much love

[badboyschiken123]

54x56=3024

[badboyschiken123]

thanks soooooooo much

[Kitty101Kyra]

Wow... Your magic o.O

[moonmax33]

tirty seven times tirty tree...?

[elham34]

i think is not working try this 47x38 64x23

[21yezzir]

WOW I feel slow but smart now :D

[anil2009cheguvara]

very nice..

[Memorandum1231]

ahh wonderful..

[RamdomVideo129]

OMG OMG OMGO GMOGMGOGMALAALALALALALALALALAL­AL

Thank You So Much :D I Was Having Like SOOO Much Trouble

in School with Math. Now this Epic Guy Showed me a super Epic

Way THANK YOU SOOOOOOOOOOO MUCH!!!

[seanpaul320aaa]

go to Brasil ll make a lot of money there once they dont Speaking ENglish they can copy you

[seanpaul320aaa]

very nice Great super easyer cool.!!!!! rsrsrsr

[taolahuy1681993]

How to do 75* 72, 82*82, 91*92 in this way ???? It doenst work

[AviarPlus]

@taolahuy1681993 No it doesn't work. it works for 72*78 cuz 2+8=10 but in the case 75*72 there is 5+2=7 and it doesn't work. This is Berulius multiplication rule.

[anil2009cheguvara]

@taolahuy1681993 last two digits shohld be equal to 10 like 47*43 in this 7+3=10, 42*48, 56*54 then it will works

[nwoooooooful]

wow, so practical!!

[ex59neo53]

his first example can be calculated mentally in less than 2 secs if u know that 2x2=4 and 3*4=12.

33*37=35²-2²=1225-4=1221

[ex59neo53]

if u know 2 things :

x²-y²=(x+y)*(x-y)

the square of a number finishing with 5 is : (10x+5)² =100x²+100x+25 =100x(x+1)+25 so will be read like x(x+1) followed by 25

example : 71*79=(75-4)(75+4)=75²-4²=5625­-16=5609 (7*8=56)

In fact in those "maths" u only have to know your square numbers calculus

[ilovejnacy]

hay its not comings yar!

because do it for 98x97 for ur method we get 9056 but the answer is 9506.

[MegaHousehunter]

@ilovejnacy The 8 in 98 and the 7 in 97 do not add up to 10. So the above method does not work for your two numbers.

[TaterGumfries]

Tricks like this here is just tricks. You're better off learnin what works for all numbers.

[alexfrgson]

@TaterGumfries you doesn't have to learn the complicated ways unless you use it in real world.

[Charisse651]

I guess it in 0 seconds lol XD

[dumbone1408]

At first I thought the video name was "Math is so sexy"

[arulknarul]

48 * 49 ?

[clemibautzen]

@arulknarul ist 8+9= ten?? (2nd condition....)

[shotaxshuba]

these 2 conditions suck

[Kevwho123]

Chances of these 2 conditions Appearing? Low

[flowerpower352]

not bad but colunm methods r better

[8449189207]

16*12=? from this method

[adamal93]

@8449189207 6+2=/=10

[8449189207]

16*12=? from this method

[Systemerror1607]

Everyone commenting are dumba**es.. Watch the rest of the video before going "OMG ##*## didn't work! Wahhhhhhhh!", must be kids just learning multiplication.

[falloist]

this is no maths...this is american maths

[ViperNeck]

Where did this start! I want to find the start!

[neochopinex]

Only works if first digits are the same, and both last digits sum up 10

33 x 37 -> 3+7=10 (first digits = 3)

56 x 54 -> 6+4=10 (first digits = 5)

21 x 29 -> 1+9=10 (first digits = 2)

112 x 118 ->2+8=10 (first digits = 11)

[TheAndrija97]

63 x 54 it doesnt work . :(((

[kgstyle89]

@TheAndrija97 it wont work because they should be in sixty like 63*67

[uthswrestling75]

28 x 52=? It doesn't work.

[SuperHighStake]

try 44*42. .. i don't get the right result .. ((

[XxstealthdevilxX]

kac did ur small brain find it hard to understand and btw this video is pretty good

[XxstealthdevilxX]

i thought his name was nazi

:)

[XxstealthdevilxX]

i thought his name was nazi

[mipiopo15]

38 x 33 ??? it work?

[motopilot322]

Pretty much only works for those exact problems..and if you do some of them in a differed order like 54 x 76 to 76 x 54 you get a different answer using his methods..

[kacforever1]

that´s one of the worst mathematic videos i`ve ever seen before

sorry man..............

[zishansharif2001]

thats fake

[GoAlienUFO]

I dont like this counting, just do the normal way.

[frankman55]

Sounds like my old kindergarten teacher. "What comes after 3, in counting? 4. isnt it."

xD

[YouSTaNzR]

28*56= ??

as you said 2*3=6 and 8*6=48

28*56=648 and this answer is wrong

the answer is 1568

thats prove that this way of solving multiplication is wrong

[M3rtyville]

@YouSTaNzR he explained that it only works if the tenth part and above have to be the same number and the last digit have to make 10. Then the trick will work. Like 34 times 36 but not 45 times 38

[DelaccRa]

@YouSTaNzR follow the condition man

[MrSmigul]

this dont work,i tryed mllion ways,this is a lie

[idolkritiq]

conditions conditions conditions ... MAGIC = Calculator!

[stardoll786]

if only i figured this out before my GCSE exams, ahh well it's helping alot ffr my re-sit thanku!

[funnycrazy000]

chuck norris counted to infinate. twice.

.

.

.

.

chuck norris can divide by 0

[gladiatorgodclassic1]

@funnycrazy000 chuck norris sucks he cant do the things you say because he is human

[CapitaoComas]

it is great, but would be better if it work on all numbers... if we need do know a diferent theory for ach numbers i think i rather do it old way...

[xTheDeathSaintx]

"see its so simple!!!" ^_^

.......O_O..........

[mohan4allpeople]

59*51=3009.... last two didgts multiplication must be necessarly 2 digits. 

[mohan4allpeople]

This is part of VEDIC MATH. its works good only when first anumer are alike and sum of units digigts =10.... 36*34=1224...

i will provide some example to understand better

12*18=216

13*17=221

14*16=224..... same way for 21*29=609 22*28=616...

And remember it works only for the numbers which satisfies the above mentioned condidtion.... also if u Learn Vedic math u can calculate fast.

for any quires mail me at mohan_sreerama31@yahoo.co.in

[Nash28ish]

sir what if 36 x 32 = ??

I use your solving but it not's correct

[maamasafe]

@Nash28ish .... 2 rules for this method...

1. first digits must be the same ... 3 and 3 , correct

2. sum of second digits =10 ..... 6+2 = 8 not 10 , then can't use this method

[KocirovD]

@maamasafe What about 62x62 ?

[frostyKB]

math is about thinking logicically ,not doing mistakes,finding the correct way to a solution

not some dumbass 5th grade trick that works in about 0.1% of your problems

[bubbagumpshady]

pardon me sir, i got a question here

let s say 59 x 51 = _ _ _ _

the answer must be in four digits, isn t it?

but how do i know the answer must be in four digits?

yes i'm very low in maths. i failed the last mid term exam. i'm here to study because i don't have any tutors.

by the way, your teaching is very helpful.

[ainatina7476]

your voice is too weird but helpful

at math

[ainatina7476]

your voice is too weird but helpful

[ainatina7476]

your voice is too weird

[djenk12345]

Every time i hear a voice like that i thing of Abu from simpsons is it only me ???

But anyway great video thumbs up :)

[omar1131]

well i really like the videos

but this is the most gayest accent i've ever heard.!

[linneamccain]

Wow! This is really cool. I especially like the trick where you stick the digit between the two numbers. How do people figure this stuff out? Simply amazing. And I agree with mrBorkD - watch the whole video people!

[AelchimTDF]

I agree with @rosas135, this method only works under 2 conditions, to apply this on an actually useful basis when doing calculations doesn't work

[syedattari]

awesome video for learning multiplication

[kissbug100]

thank you come again

[rosas135]

This method doesn't work for every number so I give this a bad reading that's y they don't teach u this in school cause it doesn't work

[onthecuttingedge2005]

I can't seem to get it to work with 27 x 26 for some reason.

[ofakar]

@onthecuttingedge2005 because 7 and 6 doesn't add up to 10

[omnicronvegas]

at first i thought why was i not taught this?? but you soon made that clear. I might astound my friends by quickly multiplying double digits...until they put forward some numbres like 302 by 409

[cfooddinner]

mentally ? how about sexually ?

[fierylava12]

@cfooddinner u fuck bois...

[jailbreakreviewer]

@op13579nv no it would be NEGATIVE 10

[Guitarledgend0123]

@jailbreakreviewer how? l -10 l = 10

[shangshangcute]

@Guitarledgend0123 yeah..that what im thinking...

[seba40PL]

man i dont understand you xD

[imaedu]

It's not really good as it should control by certain number. Isn't it?

[sheao1]

WOW i hate math but i love how it works, school teaches its the hard way

[wouter1246]

you have 10 kinds of people:

those who understand math and those who don't

[chrissline77]

Simplify | 2 + 3(–4) |.

[op13579nv]

@chrissline77 It's 10, isn't it?

[Usefulknowledgeable]

gangsta

[LabambaThe100]

try to watch my videos just for entertainment. :D.. haha

your formula are cool.

[FanjitaTowels]

This method is practically useless as you have to check to make sure the conditions are met first before applying it, and the conditions won't be met often.

[hibasaab1]

can u do a trick 21 multip with 56 or  0r 56 multi with 16 or45mult with91

[imtheoptimator]

I'm not terribly sure what the pedagogical benefit of this is. There are many arbitrary situations that can lend themselves to particular methodologies for the purposes of speeding up the calculations. I can't imagine many people are going to go out of their way to look for these extremely particular situations, and if they do, they've spent time that they could have used simply doing the calculations in a universal more methodical way.

[crazyflower22able]

It is so hard why why .... I love maths I'm trying to know these tricks but it's just soo too hard :'((( *cries*

[weirdalien26]

the ending killed it, but good strategy :)

[ikkyuuu1]

`good vid



[v4liumfrance]

That's not maths.

[doomyhacker123]

come on if you believe in that,im a monkey,HATZI make tutorial of number that dont have same first number,its simple,its not real

[omscharf]

I cant believe i went to youtube for math

[MrIllegub]

/watch?v=CnxQ5YOFc7k <--- Math Calculator Works Evrything Even Trigonometry And Pythagoras!!

[gracegirly1]

No Good numbers scare me it makes my head hurt

[MAHARUSAMA]

if i follow ur way then there are so many numbers which cant be solved from this same technique like 84*2 ?

plz do reply

[labalabalabamba]

@MAHARUSAMA did ya even listen to his video? he said that there are 2 conditions

1) the first digit/s should be exactly the same

2) last digits must sum to 10

obviously, there ARE numbers which cant be solved by this shortcut

[mrBorkD]

For all the idiots out there, we know it does not work on all numbers. He clearly explained the conditions the multiplication has to have... Just watch the whole fucking video...

[MAHARUSAMA]

u r rite i am agree with u...

[lozada412]

the 3 goes between the sandwich?

[Ashizimack]

this method 46 * 43 = 2018 by calculator: 1978 =] In fact not all numbers work here;] but method interesting

[nubsmacker]

@Ashizimack he said the second digits have to add to 10, 6 + 3 is not 10

[thelastair1]

brain crash it stoppt instantly now going to sleep

[Z666ful]

666 x 908=?

50 x 20955=?

1 x 1 =1

[supergreatsuper]

@Z666ful The units digits must add to 10

[supergreatsuper]

@Z666ful The units digits must add to 10 and the other digits must be the same Weren't you listening?

[mohan4allpeople]

@Z666ful : Its just one part that we hav shown video..... if u want to calculate fast .. learn vedic math. Math is nothing but solution and rules.

know it before u comment... any any doubt.. mail me at mohan_sreerama@yahoo.co.in

[R9LegenderyFenomeno]

It's handy for small calculations, but what about 25699*3699, you'd still need a calculator, no?

[BrutalValor]

By your method.

56x53 is 3018

By the calculator, it is 2968.

[WatchPlayDownload]

@BrutalValor Its 56x54 not 56x53.

[BrutalValor]

@WatchPlayDownload

No,no. I did a different one.

[WatchPlayDownload]

@BrutalValor :S ....You were saying that he did 56x53 when he did 56x54. Which is why you got a different answer.

[BrutalValor]

@WatchPlayDownload

No, I did 56x53. I know he did 56x54.

[reefpov]

@BrutalValor

u don't fulfil the 2nd condition which is

"the second digit of the first number when being added with the second digit of the second number will be equal to ten"

[McMuffin12100]

Dirty deven dimes dirty dree

[sfish35]

this is so easy

[Haledjian1234]

You dissapoint me!!!!!!!!

[mamasaymakossa]

I disagree with the title.

[lovetosplash]

on 21x29 how do i know i have to put a zero



[loadrunnerste]

@lovetosplash 10 x 10 =100 that is the minimum number in multiply 2digit numbers tougether, you always need 3

[PlayboyHZ]

I cheated.. I started to calculate it as soon as i saw the question.

[interpird350]

Never say math is easy.

[Lukaser5]

This trick only works if:

1.Last digits add up to 10 (5+5, 7+3, 2+8)

2.Digits before last are the same

BTW not only 25 * 25 or 47*43 will work, but also 126*124, you multiply 12 by 13 and add 24, which results in 15624

[araliric]

I think it only works when the first digits of the 2 factors are the SAME.

23 x 27

76 x 71

etc...

[TheMillerBenz]

Jebalo majku ako meni ovo ulazi u glavu ....exxexeexexex Belgrade

Hey everyone I just finished creating a math tricks website for those who need help improving mental math and basic arithmetic skills. Please check it out and let me know what you think of it. My site is mathtipsandtricks . com

[321beth321]

i cant do mental math... makes my head hurt >.<

[hlc123333]

i do say fak away man

u dont tell anything i tryed some digit number with ur trick

it doesnt work

i saw many this guys videos

and i do say, it didnt give a shit

like 92*52

46*73

etc

many doesnt work i depend anything depend...

[Hacides]

no



[sasukerocks51]

i did da trick 45 x 23=2015?

[reedy111111111111111]

but the 7 an 3 has to round up to 10 for this to work

[iPhanthom]

his accent is tremendous

[orbanemanie]

fake now look u have 37*33=1221

if u now have 37*93=1221

so... u fail

[firefrostpeacemaker]

@orbanemanie yo genius, 37*93=3441 not 1221. so... u fail.

[max066447]

pls make more.

[CodeMidnight]

Thank you soo much! I didn't know how fast person can calculate :)

[best496]

shut up. meth is not eesie is to hard forr tha norrmul persone too understend. im supposd too be a gienus an eiven i i downt understend

[byulset]

You have to do 36 and 34 3suppose to be same (tens place) and 6plus4 is ten (ones place always make ten)

[chba]

How about 67x 83=?

[Seryal001]

@chba 6 is not equal to 8; the 10's columns must be equal.

[9898strongman]

very useful thank you i used to suck at math but now i am just amazing at it

[killer14648]

45*25 is NOT 2025 !!!!!!!!

[li088]

21x22 cant do this one like you say!

[CodeMidnight]

@li088 2+1 are not 10 second digets have to be 10 together

[Armorith]

doesnt work all the time

62x43 = 2666

in your way it makes 426

(=

[kimsy12322]

i tryed 12x16 and nt work

it says 212 but it's the wronge answer, the correct 1 is 192

[crazytank3000]

@kimsy12322 lol u did it wrong then

[golvendeannie]

@kimsy12322

but 2+6 aint 10

12*18 must work

2

12*18 = 2 16

[golvendeannie]

@kimsy12322

but 2+6 aint 10

12*18 works

2

12*18 = 2 16
