1=2 !!

Let, a = b

So, a-b=0………………………… (i)

Multiplying both sides by 2 we get,

2(a-b) =0

2a-2b = 0

From (i) equation we can write that

2a-2b = a-b

2(a-b) = a-b

Omitting (a-b) from both sides we get,

2 =1

Friends, have you got the mistake in this math?

* See, As 2(a-b) =a-b it means that 2(a-a) =a-a or the value is 0. But, in mathematics numbers cannot be divided by 0. So, the process is impossible.
