My favourite mathematical fallacy ever goes like this:

a = b

Multiply both sides by a,

a² = ab

Subtract b² from both sides

a² - b² = ab - b²

Factorise

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

Divide both sides by a - b

a + b = b

As stated in the beginning, a = b, so

2b = b

Did you spot the mistake? Answer under the cut

The mistake is after factorising. You can't divide both sides by a - b, because if a and b are the same that would mean dividing by 0, which is undefined in maths.
