Amazing math trick proves 2=1!

Sort:
linus9113

Let...

a=1

b=1

That means

a=b

multiply both sides by a

a2 = ab

Subtact b2 from both sides

a2 - b2 = ab - b2

Factor

(a+b)(a-b) = b(a-b)

Divide both sides by (a-b)

(a-b)  ///// (a-b)

        Cancel

*crosses out both (a-b)*

a+b=b

If

a=1 and b=1

Then

1+1=1

2=1

EVERYONE! THIS IS A JOKE!

another:

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

2=0

another...

a=b

a^2=ab (multiplying by a)

a^2-b^2=ab-b^2 is equivalent to:

(a-b)(a+b)=b(a-b) (factorisation)

a+b=b (dividing both sides by (a-b))

a+b-b=b-b (subtracting b from both sides)

a=0

so all numbers are equal to zero.

 

 

Everyone, you can do more math tricks. Very fun :)

Wtf? your stuff?

For all you who can't figure out the mistake, highlight below

 

Each "proof" involves dividing by a-b which equals 0. Since you can't divide by zero, all the proofs are null and void.

ha ha ha i am laughing a lot

1+1 =2

they know that...

LordJones3rd

here is a good one: a=b

ab=aa

aaaa

aaaa

therefore a-b=0

linus9113

uhh but that's true.........

1-1 = 0

2-2 = 0

3-3 = 0

4-4 = 0

it goes on and on...

LordJones3rd

of course it is true. you would never believe it if i said a=b

a>b

lordjones why u think i copied it? cuz i didnt. maybe u just copied mine!
