///////Find The Mistake????????(only for people who love maths)

let a=b
therefore,ab=b^2
so we can say,,,,,,,,,,,,,,,ab -a^2= b^2-a^2
after factorization we get,,,,,,,,,,,,a(b-a)=(b-a)(b+a)
therefore,,,,,,,,,a=a+b
since a=b,,,,,,,,,,,,,,,,,,a=2a
therefore 1=2

TopNewestWell, it's same as cancelling zeroes on both sides, which is not allowed in mathematics!

Thus,

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

the above equation is same as:

a(0) = (0)(b+a)

Hence, it will be incorrect to slash off zeroes from both the sides!

well done

We can't cancel a-b from both sides without writing that a-b=0 can be a solution.
