Dividing by zero makes any number equal to any other number. It renders the number system meaningless.

Suppose a=b:

a^2-b^2 = a^2-ab = a(a-b),

but

a^2-b^2 = (a+b)(a-b);

therefore,

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

and dividing by a-b we have

a = a+b.

Let a = 1. Then 1 = 1+1 = 2.

Isn't that special?

Yours is the proof that satisfies!

Similarly, in truth-functional calculus, allowing both p and not-p permits the generation of limitless propositions.

Once one accepts a lie as truth, one can believe anything at all without evidence at all. The socialists teach us that.
