1=3 right? Is this not correct?
Where is the mistake in the below explanation?

Kaustubh Katdare'x = y' , which means Apple = Orange.

Anoop KumarIt's actually
3*0 = 0 -

Right.Anoop KumarIt's actually 3*0 = 0
The last but one step can be elaborated as 3 x 0 = 1 x 0. The fallacy is that dividing both sides by zero gives 3 = 1.
Dividing by zero is an invalid operation. -
zaveriCheck step number 5:
it goes as 3X=X = 3Y = Y
is this supposed to be 3X-X = 3Y - Y ?
if it is, then the mistake occurs at step number 6.
Step number 6 would correctly go as : 3X - 3Y = Y - X -

Kaustubh KatdareThe first line itself is wrong. When you say, 'x=y', which means 'x' and 'y' are one and the same thing. So it can be extended to any level and prove anything equal to anything.

Not really. X can be the number of girls in a class while y can be the number of desks in the class. The real issue is that division by zero is not a defined mathematical operation. The whole thing is set up as a confusing buzz, hiding the wrong operation.micheal johnyes -
madhu27step1: x=y
but in step5, 3(x-y)=(x-y)
which means, 3(0)=(0)
the mistake occurs here..😎 -

Sir nailed it. Simple and elegant explanation. -
shiwa436The above thing is just like.....
If a=b , b=c then a=c
Implies 2=root(4) , root(4)=-2 then 2=-2 -

In maths there is an equality and there is an identical equality.
Both +2 and -2 are roota of 4.
So 2 = Sqrt(4) does not mean 2 is identically equal to Sqrt(4) -
shiwa436#-Link-Snipped-# ramani.. Sir,
A small explanation will convince us, both the things are just outta incomplete application of actual rules.... -
Kaustubh KatdareThis is the simplest explanation:
The 'proof' starts by assuming 'X' = 'Y'. Since X and Y aren't defined -> you should be able to prove almost anything; because it's based on 'assumption' that X = Y. -
Ramani Aswath
Sqrt(4) = +/- 2shiwa436#-Link-Snipped-# ramani.. Sir,
A small explanation will convince us, both the things are just outta incomplete application of actual rules....
Using Sqrt(4) to mean +2 in one part of the argument and -2 in another part leads to an inconsistency beca
The original problem has a different issue. That argument uses division by zero, which is not permitted in maths. -
Shashank Moghe
The problem is not the assumption. Mathematics gives us the full liberty to assume anything that fits the rules (and here assuming two variables are equal is not against any). The problem is the step (tricky step) which is so common to many such "proofs" which claim flabbergasting results to be true. This tricky step is intentionally introduced because it skips the attention of most amateur proof readers: and the step is called "division by zero", which is not defined.Kaustubh KatdareThis is the simplest explanation:
