  • You are a stupid F**k ...

    C = B - A / (B - A);
    C ( B - A) = B - A; not C ( B - A) = (B - A)^2

    • NO...

      You didnt understand. He didnt use "/" to divide !!!
      Ok if you want, just ignore the "/".
      __

      the trick is B-C-A = 0 . So you can't simplify A(B-C-A)=B(B-C-A)

    • yep

      this formula is all screwed up

      By gobi 1176690485
    • wow

      easy trick
      A(B-C-A)=B(B-C-A)
      B-C-A =0 so u cant simplify

    • hmmm...

      The expression " /(B-A " means that you multiply both sides of the equation with (B-A) in this case SIDE1=C and SIDE2=(B-A) so if you multiply both will be: C*(B-A) and (B-A)*(B-A) than C(B-A)=(B-A)(B-A)... what's the problem with this you stupid f**k ???

    • pipidepitic....get out of your arse

      C = B - A / (B - A) -> C ( B - A ) = ( B - A )^2

      Thats not perfectly logical, in fact, thats just plain wrong!

      If you multiply though by the ( B - A ) you just cancel out the bottom of the equation, the top isn't squared. Go to F**king school and show a maths teacher, they'll show you its wrong.

      If you try and get C on its own from your fucked up answer then you'll end up with C = B - A.

      Ironic isn't it that you slated the guy that got it right?

    • sir Regano...

      before using so many **** try to look more carefuly at the video and stop beeing so smart with me.
      i will eplain to you why :
      in the video the first line C= B - A / (B - A)
      "/" it is not devide ...the ecuation is C= B - A and then he is using "/" if you want you can use "|" or "" telling he will multiply in both sides of the ecuations with (B - A) witch becomes C(B - A)= (B-A)^2.
      So before trying to show me that you are smart you better make sure that you are.
      i bet you're an american

    • i don't understand how come you got 4 vo...

      i think to many stupid people are watching this site. grab a book and start learning instead of loosing your time on the internet.

      C = B - A / (B - A) -> C ( B - A) = (B - A)^2 is perfectly logic

      the only problem with all these 1=2 jokes is that you are not alowed to devide if B-C-A =0

      By pipidepitic 1175448043
  • instead

    of using the letters to represent the numbers why dont you just use the numbers themselves

    By funkybeaner 1175483454
  • YOU CAN NOT DIVIDE BY ZERO

    BASIC OF MATH SAYS THAT EVERY EXPRESSION WHEN DIVIDE BY ZERO IS IRREGULAR EXPRESSIONS
    IT IS F**kING RULES OF MATH (BASIC).
    IN MOMENT A(B-C-A) = B(B-C-A) EXPRESSION IS VALID
    4(5-1-4) = 5(5-1-4) BUT WHEN HE USE SIMPLIFY, HE USES DIVIDE OPERATION WHICH IS NOT VALID FOR ZERO!!! YOU CAN USE EXPRESSION A(B-C-A)/(B-C-A) = B BUT WITH SATISFACTING RULE THAT B-C-A != 0
    IF YOU CHANGE PERHAPS C, STARTING EXPRESSION IS NOT EQUAL......

    By dovlacba 1297127972
  • IT CAN'T BE

    if you use letters... for B you can use every number and it will be the same...
    A=4
    B=6
    c=2

    C=B-A
    C(B-A)=(B-A)*(B-A)
    CB-CA=(B*B)-2BA-(A*A) / (-A*A)
    CB-CA-(A*A)= (B*B)-2AB/ +AB
    AB+CB-CA-(A*A)=(B*B)-AB/-CB
    AB-CA-(A*A)=(B*B)-CB-AB
    A(B-C-A)=B(B-C-A)
    A=B ==>
    4=6

    BUT IF YOU TRY WITH NUMBER IT WONT BE THE SAME ;)

  • What is wrong with you!?

    4 IS NOT EQUAL WITH 5 THEREFORE 2x2 ISN'T EQUAL WITH 5! LOL!!!!! what kind of "stupid" are you!?

    By Immortal1995100 1296937163
  • He is wrong

    C = B - A / (B - A) FROM THAT
    C*(B - A) = (B - A)*B - (B - A)*A
    NOT C*(B - A) = (B - A)^2

    TNAH...
    1*(5-4)=(5-4)*5-(5-4)*4
    1*1=1*5-1*4
    1=5-4
    1=1
    WHEN YOU MULTIPLY BOTH SIDES YOU MULTIPLY EVERY NUMBER IN THIS EXAMPLE

  • Duhhh...

    I don't get it ....

    By VinnieH 1296932486
  • Manipulation is ok, but...

    So your manipulation with signs is fine, but in the end your expression B-C-A=0! So you divided by zero which is not allowed.

    In the end 4*0=5*0 which is correct (0=0) but dividing by 0 and saying 4=5 is dead wrong...

    By dingo_bastard 1296915392
  • :P stupid

    C=B-A /(B-A)
    C(B-A)=(B+A)^2 becouse -A*-A=+A

    By boavranjes 1296852793
  • Stupid....

    A*0=B*0
    You can not divide by 0

    By stefan_kuciq 1195400599
  • no dudes

    no dudes it is wrong bec. (b-a-c)=0

    and if 4*0=9*0

    that doesn't mean that 4=9

    By --omar-- 1195136820
  • ...

    doesnt matter what you do... it will always be 2x2=4

    just like if u add 2 fingers plus 2 more fingers on your hand.. it will equil 4 not 5..

    and who would wanna use that big long formula or wach u do it? all for a simple question 2x2=4

  • nerd online

    u cant impress teachers with dat.

    By DogBeast 1180450507
  • everyone needs to read this

    you can divide by zero
    i can't even imagine why not
    the answer of dividing anything by zero is zero
    technically it should be infinity but since zero is not an entity by itself, the answer will always be zero.

    the real maths law that nullifys this is that both sides of an uneven equation are even when multiplied by or divided by zero.
    because he made no mistakes
    just so happens the every equation works out when that happens

    By the immortal martyr 1178320344
    • uhhhh im not gud at maths but...

      I agree, if u do somthing with a number and zero, the result will be zero or the number.
      To be more logical, dividing and multiplying results zero(or infinity im not sure), and plus andm inus results the other number.
      OR infinity but im not sure were not learning that in school yet.
      for example:

      5X0=0
      5/0=INF.???
      5+0=5
      5-0=5

      ahh omfg
      i overheated my brain!

      *dies*

      By DogBeast 1180450217
    • ...

      You may not divide by zero. Infinity is an adjective, not a number. It describes the fact that when a number is divided by ever increasingly small number the result is a larger number.

      Look at the equation:
      y=1/x

      For smaller values of x, it results in a large value for y. y never reaches infinity, because you cannot divide by zero, only get very close. There is a limit to what you can divide by, and it is written like this:

      limit x-->0, y=infinity

      You can think of it as 1/0 is approximately infinity.

    someone smack this faq please

    • what

      Ferquently
      Asked
      Question
      U wanna get smacked?

      By DogBeast 1180450329
  • LOL

    I know ... I'll make all the numbers turn into one eventually then exponentially multiply them to make .... err one !!! I'm a genius .... haha wow

    By Bobby_54 1175466274
  • this is F**k

    its not cool. its kind of silly and stupid methods. i think you want some time pass!!!! heheheheh

    By kesang6 1175440966
  • you may not divide by 0!

    that's what's wrong

    By axel_da_man4real 1175439825
  • Stupid divided by zero trick

    No matter how many times you make stupid calculations before you divide by zero, result is the same.

    By onse 1175382361
  • Agree with cristi4u

    If B-C-A didn't equal Zero, the solution would make sense. Good math problem to get you thinking.

    By ClownsUnderYourBed 1175378039
  • lol

    A(B-C-A)=B(B-C-A) it's like
    4*0=5*0 ----true but u can't cut out 0 !!!!!!!!!

  • wow! nice!!!

    you earned your 1 star for S**king in math.

    By MAMOHT 1175475118
  • What a F**k tard...

    I completely agree with XxxooxxX, do your F**king maths! and i suggest that to everyone else on here who thinks its "magic" and doesn't know a thing about maths.

    By mastertidus 1175440754
  • All it means dumbass...

    Is that the first equation is untrue. Quit trying to get others to do your homework.
