Amazing Math Trick 2=1!! BUSTED

[QSHePoKaTTi]

how to hell i get there??

[felipetam]

two silly mistakes made..

first dividing by zero, that never works.. that was on the fourth line (excluding the value definition)

second, (a+b) || 1+(-1) should have yelded a result of 0 not 2 as in the video.. that was on the fifth line...

the guy doing the video seems to have forgotten he defined b=-1 before beggining..

dumb stuff

[lennic95]

I feel sick looking upside down! :{

[TheAwesomeBrandon]

Did you really copyright this video?

[lightpino]

I understanded it, untill you wrote the || thing, what does that mean?

[dwarduk2]

@lightpino On the other side of || was what he was doing to the equation, like multiplying both sides by a.

[Ormabala]

a-b=(1-(-1))=2  a+b=(1+(-1))=0

[Problemsxx]

a-b = 0 and you cant divide by zero

[krizkrytyk]

lol (a-b) = 0 cool dividing with that.

[fredb3]

Yes when you divide by 0 which is what he did.

He went wrong in his equasion,[ (A-B) = 0 ] he technically divided by 0 to make the "proof" that 1=2 by removing the (a-b)

Where a=1 b=1

(a-b) = 0

By removing (a-b) you are dividing by zero and you cannot do it, resulting in the subsequent steps being wrong and making this mathematically unsound.

When accurately written, this should have any 1 of the equasions minusing the rest and = 0 other wise it is NOT equal.

Sorry try again

[CyberianIce]

You can not divide this equation by "(a-b)" because a=b so that would be division by zero by all means - line no. 4.

[ottoenie]

dude, what are you thinking? do you have any idea how many years of research they do for specific math problems, and you think that in some hours, you've found an error? there aren't errors in math, it is 100% correct, and if there is an error, (which i doubt) the world is an epic fail.

think about it.

[Kewickviper]

Well I see your problem there sonny. Trying to divide by a - b looks suspiciously like trying to divide by 1 - 1 = 0 which tends to break equations (and hearts)

[eojox118]

Good vid. I came to an equally correct but less elegant disproof. I realised that the origonal "proof" seemed to imply...

2 x a x 0 = 1 x a x 0

...which of course is true, but doesn't itself imply what was claimed.

[iainmcke]

joonasal, you've ruined the fun of it now =( I enjoyed watching people try and fail to guess where this trick goes wrong, now there's no fun in knowing that the answer! Some of the responses people gave on other videos were great lol (as in they failed in a funny way). Less so now. Spoilsport =/

[Jackpkmn]

how is it helpfull to write down a^2 when a=1 that means 1^2 wich is 1*1 witch is 1*1=1 becasue when you multiply a number against 1 its the number you started with, so in the end all the a^2 and b^2 is just saying 1? or am i msising somthing here.

i'm also wondering then would a^b = 1 when a=1 and b=1(or two even)?

[grabich]

actually, on math-related universities, we use 1 like 1, but in fact it isn't true. it can be 1=1.0000...0001, so things like this aren't true. there are some proofs with limit of a function. but I don't like to argue about that because I'm not that good mathematician.

[TheRabidDeer]

Math is about manipulating numbers, there are many times when multiplying or dividing by 1 can result in a drastically different/easier to solve problem. At a basic level such as in this video, it doesnt really change anything though.

[GriffyGriffGriffin]

MICHAEL JACKSON!!!!:DDDDDD

[tomhasz666]

In this part of movie 1:48 / 3:08

You are dividing by 0 (a-b)=(1+(-1))=?

Its unacceptable in maths ;) You know One of the sticky rules

[fakieism]

@tomhasz666 did you know that this is a RESPOSNE do another guy's video? he knows that he is dividing by 0...try to watch whole video and you'll understand

[HakuGotStoned]

thats what he's saying. This "amazing math trick that proves 2=1" doesnt work cuz you have to divide by (a-b), what means (1-1)=0. And hes showing that in the end of the movie...

[MISTofDAN]

@HakuGotStoned No you have to simplify the problem before plugging in numbers.

[hafik007]

Anyone who has ever done such a calculation had to see that it is wrong to devide by (a-b)... algebra FTW!

[x1x2x3ct]

omgay lol what a fag !!1

[SpyrosFgs]

joonasal this is not a trick. it is really happend in algevra. it is when you work with limits...I do this kind of maths here in Greece this year. I am 17 years old.

[talcodes]

Why is age relevant?

[SpyrosFgs]

because you learn maths by age.....you will note learn this things at the age of 10 here in greece....in other countryies you don't learn about the limits at all in school...

[daemonpoet]

@SpyrosFgs

I don't know about you but I was taught you couldn't divide by zero when I was in the third grade here in Texas; I was 7 at the time.

[SpyrosFgs]

@daimonpoet ...do you know how to work with the limits? of you don't ok then. but I do....when you have....something/0 f.e. 5/0 or 251/0 or 0/0 then if you want to come to a sollution you work with the limits. I can't explain it with words....

[mrbinary1001]

No you're right. You couldn't back then, but you can now :-)

haha.

[Surfurplex]

Man.. that was obvious, shame on me who didn't see that <.<

[vctop101dunk]

a = 1, b = 1

why u need 2 alphabet for a same value?

i think it would be an error if u use 2 alphabet for a same value.

2*

[DatWonGuy]

It is VERY possible for two variables to have the same value. No rule says they can't. A variable can be ANY number.

[vctop101dunk]

r u right, there is no rule says that. but i think most of the 2 variables with a same value would cause errors and use for tricks. AND there is a "zero error"...

[MediaOwnsYourMind]

all variables have any value. so any two variables can have the same value.

[NovaN0va]

@DatWonGuy But, on the paper, he set the values for A and B.....thus, your argument can not be applied to this.

[ikalpo]

@DatWonGuy A variable can't be ANY number if it says that it is a certain number.

[lordwhite0]

@DatWonGuy

DatWonGuy has a point, as we are doing these calculations, we assume that the numbers are variables (a,b,c,z,¿,☻,☺,etc...). So I can say that A=B even if A=999,999,999,999 and B= -4,647,383,289.937

[morbideddie]

@lordwhite0 well no. you can't just pick 2 numbers. one is dependant on the other and vice versa, that's what equations are for. finding how one variable alters when the others are altered. so if you start with a=1 & a=b then guess what, b=1. not rocket science.

[RadobotFubotic]

a+b=0 ?

1+1=0 ?

1+1=2 !

a+b=2 :)

[MetallicaRepublic]

shit song

[jokkmokk1100]

U can't devide something by zero!

a-b=1-1=0

can't do it!

[bobie1704]

That's the point of this video...

Watch the whole video next time...

[icefall1793]

omg what jookmokk is true and he has -3, this shows how stupid can youtube ppl be.

OPEN A ALGEBRA BOOK! Algebra may look pretty, you can do many things, but when it comes to domains and restriccions all your calculations mean nothing.

[DLee594]

He has neg. 3 because dividing by 0 was the whole point. He disproved the trick by showing the only way it's possible is if you divide by zero which is impossible.

[mythdoors]

OH SHI-

[Trobit]

Another explanation rather than "you cannot divide by 0" is that X1 = 1 and X2= -1 (the straight lines equations) are parallel, so they will never cross, so, when you try to solve it by any equations system, you will get u =/= v ("=/=" means not equal XD).

[lordwhite0]

@Trobit lol Do you mean this symbol? ≠ I copied it from a keyboard symbols page on google. It's a symbol like when you use alt+168 to get this ¿ or alt+8877 gets you ¡ as opposed to the normal ? and ! XD lol

[Trobit]

@lordwhite0 Nice... thanks man, I'm not quite used to ASCCI nor unicode, but that's a nice tip dude...

[TheManurules]

a-b = 1-1 =0

You are not allowed to divide by 0.

[looney1023]

technically you can, but then we get infinity=infinity

[TrueHonors]

No need to prove something you already know is false.

[kirbyphanphan]

yeah my math teacher told me this morning

[Shimoc]

lool....it's like saying that 2*0=1*0 => 2=1 :))

[microsoftandryson]

actually doesn't need to divide them.

you see, (a-b)=(1-1)=0.since it is zero, you don need to divide them anymore.. :)

anyway i enjoy it...

[WebMuseum777]

The proof starts with statement a=b, So you cannot divide by (a-b)...

[228player]

you proved you can't spell

[bahamutzeromusashi]

f**king winner

[ronacin300]

thanks spudd86 but everybody knows that. If this is a true algebrac expression and when you are solving fraction of polynomials, you don't think of whether a=b, right? you apply values at the end of the simplification.

In this case, what we are trying to prove is whether this equation is valid or crap-- which turnd out crap because there's no variable. It is simply arithmetic 1+1 =2

[macklegend]

You do not apply the values at the end of the simplification if you have already established that a=b.

Say you didn't first state that a=b and worked through the problem. That would mean that you would apply the values at the end, however, you wouldn't have the first step of the equation where a=b.

Basically, what you say at the beginning affects what you can say throughout a proof.

[jojo60056]

From the very beginning, this equation is totally wrong. There's no variable in the equation. This is not an algebraic expression but arithmetic.

it is simply a + b = 2 because a=1 and

b = 1. The equation will be true if one of the letters is unknwon value, say a=? and b=1 or introduce another letter with unknown value, say C=? . so I don't know what the equation is trying to prove if every letter has definite value.--- there's no variable.

[spudd86]

no, even if they are unknowns anything you get after division by (a-b) is true only for a≠b

the algebra here prooves nothing because it is not valid, that is the point of the video. HOWEVER it is important to keep this in mind whenever you are doing algebra. Any time you have two unknowns (say a and b) and you divide by (a-b) you have implicitly assumed a ≠ b, if it later turns out that a MUST equal b then you do not have a meaningful answer

[jojo60056]

any number by zero is undefined.

hotindianpixie said that "You are not to assume the value of each variable in the equation at that point. "--- that is true but remember, there is already assumption from the begining of equation and that is a=1 and b=1. In that case, anything you introduce in the equation must agree to the assumption a=1 and b=1. dividing both side of the equation is forbidden because we know a-b = 0.

[laronda10]

2x-2y=x-y

how did you turn that into

2=1

[laronda10]

i did since x=y,

than x-y=0

and 2x-2y=0

so 0=0 its called checking your math

[uffshadow]

(a+b) = (1 -1) = 0

DIVISION BY ZERO NOOOB not defined

[hanntyler1]

You've come up with nothing new...

2x-2y=x-y

2(x-y)=x-y

2(x-y)/(x-y)=(x-y)/(x-y)

You are dividing by x-y. If x and y are the same, which they are as stated at the start, then you are dividing by 0, just like the other one........

[xyresicpeace]

what happened to the -2y in the second line? it just disappeared, you forgot to add to both sides

[hulksmash05]

all i was listening to was the song, the math didnt make any sense 2 me sorry.

[Miron111111]

yeah... those divisions... they can be really dangerous when skin head is singing in the background :)

[gamwtinanarxia]

man the angle you shot this is hahaha ...

[Gaspacho79]

You write the numbers starting from below!!

Lol

[bovko1]

Nice shooting angle lol

[subzero810]

imaginary infinitive

[Whopzer]

Lol, I looked at this shit until I saw that you were a woman.

[SlimMargelov]

The mistake has been admitted, when brackets were reduced(a-b):(a-b) / (a-b) =0/0, a=b

[SlimMargelov]

Народ ошибка была допущена,когда сокращались скобки (a-b),т.к (a-b)/(a-b)=0/0,поскольку a=b

[joonasal]

I'm very sorry but I don't speak Russian.

[HIMkidHIM]

People error was committed, when brackets (a- b) were reduced,(a- b)/(a- b) =0/0, since a=b

[hulksmash05]

what is the name of song.

[amit44373]

A-B=0 u cant division with zero

[joonasal]

But Chuck Norris can!

[Agni2222]

which michael jackson song is this playing?

[patya831224]

a-b=0 come on:)

[eismar5]

...divison by zero, 90% of all humans will never get it? x)

[joonasal]

True, true!

[PianoKwanMan]

hold on division by zero is infinity...

[radakina]

1-1=0 you cannot slip by 0 or divide or something else ...

[ComradeSephiroth]

This is a classic algebraic sleight-of-hand: hide an illegal operation (such as division by 0) behind a bunch of figures so what you are doing looks legitimate.

It's like the one where 1 = -1:

1 = sqrt 1

= sqrt (-1 * -1)

= sqrt (-1) * sqrt (-1)

= i^2

= -1.

Trouble is, you are crossing from the real number world over into the imaginary world and then coming back to reality. This is forbidden.

[jesusxfreak]

Also, you cant reverse the effect. Like to say:

1=-1

(1)^2=(-1)^2

1=1

That's assuming that the sqrt(1) can be either 1 or -1. While true, they cannot use them interchangeably.

[hulki]

right :D

[PakistaniDude3000]

ComradeSephiroth,

Crossing from the world of reals to the world of complex numbers and back again is forbidden?!?!?!?!? Reals are a proper subset of complex numbers!!!!!

The problem with what you posted is that you took the wrong branch of the sqaure root. You need to take the branch sqrt(-1)= -i to get the original branch of the sqaure root above.

[A0G7]

its just 2 isn't = 1

[FarSol02JL]

lol the problem is that when you clear (a-b)

as it is acutally multypling goes the other member dividing and, if a=b, then a-b=0, and a division that includes 0 is an imaginary number.

but its a good trick anyway :D

[Toybox10321]

No shit, you just busted a theory that obviously isn't true, even when he says it's a joke

1 star, no apologies, no offense, but I think that disproving things that are obviously fake just makes you seem like an ass,

(if someone responds to this they're gonna call me an ass just because I used the word)

[1337ASM]

like no one else knew tht.. u think ur so smart.. well i got a news flash for you walter cronkite.. you aren't !

[1LastDude]

Sweet!!!! U BUSTED IT

[insertlettucehere]

nice catch

[bejbikiler]

sorry that I gave you 2 stars, I did it by accident

[joonasal]

Better than nothing I suppose =)

[1LastDude]

o yea and wat song is it??

[joonasal]

They Don't Care About Us - Michael Jackson

[OmegaEclipse]

That was awsome. just awsome.

[R44F4Y]

amazing

[annbil]

the flaw is at "a+b=b" that cannot be true.

that could only be if a=0, but you said at the very beginning that a=1

[moomeen770]

it is an old fashion trick divide by zero

you can proof every number equals evey number

[joonasal]

it says BUSTED not PROOFED

[bumpetydump]

*proved

[R44F4Y]

it says busted i can see it

[douchsandwich]

only chuck norris can divide by zero ... (nerd)

[NanoFight3r]

wow, you really suck

[Budanka]

Ahh... everyone can divide by zero...

[edgar20006]

[bandgeek58965]

If you divide ANYTHING by zero, including zero, it is an undefined number, that doesn't exist.

[utubecrazyharish]

boyyyy...this shit is jus plain silly!

[GuitaristNSkater]

cant cancel both sides. you can only if they are not multiplied by anything.

[BatBatt1e]

hahaha you have do the same error as the other video YOU GUYS ARE REALLY BAD

[yamilyamil]

Not only that the trick is obnoxious, what makes it even worse, is that you had to think while developing it.

[alucard1201]

dont divide by zero, shit explodes when u do that

[fuzzymilkdud]

thats exactly what my precalculus teacher said! lol!

[girgog]

you cant divide both side to "0" the error is this...

[ofeyofey]

(a-b)=0 so when you cancel (a-b) from both sides it is the same as dividing by zero which can not be done.

[joonasal]

I just copied that part from the original, there will be new version of this soon also

[ofeyofey]

What does double pipe || mean? Is some kind of modulus?

[baaba1012]

It means that something is done to the both sides of the equation. For exmple 2X=4. You get X by dividing the both sides with 2. 2X=4 II:2. X=2

[baaba1012]

siis oletko sä kuvannu tän? perhana tää on kumma. heti puhumaan pukoselle! :D

[joonasal]

joo olen ;D

[clevercookinchef]

Well, you put in the effort, so I'll accept it as a response.

I don't appreciate the ending though... :(

[joonasal]

thanks, I'll fix the endind, don't worry! just gimme few days..

[clevercookinchef]

Oh, no, there's no need go through the upload process just for the ending.

I'm fine with it.

[joonasal]

Please, I can do that, no big deal. It's very easy for me to upload videos. Strait from iMovie. And it's easy to make that "ass" to disappear. Also I gotta fix one thing in the video, there's a little writing error in it. Some, like me, may not like it =)
