Howdy,
In this post we will look at a mathematical fallacy that enables us to you prove 1 = 2? We will in fact prove that 1 = 2 using a series of steps, one of which has a flaw. Your task is to identify the step that contains the flaw. Check the video below for the steps that prove 1 = 2. This example by the way is one of the best examples of mathematical fallacies.

In step 4 you subtracted from the right side but not the left.
Last step.
(a^2-ab) =0, hence shouldn’t cancel it.
It’s like saying 2*0 = 1*0.
Cancelling works when you divide same numbers leaving 1.
(x/x)=1 but x should be non zero number.
