EVERYONE! THIS IS A JOKE!
TRY TO CATCH THE MISTAKE
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 :)

sounds very similar to a post i did a couple of minutes ago...
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.
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
