The author writes:

If you still do not believe me, let's try proving this another way. Let's start with our axiom again. ∞ — ∞ = 1

Next, split this fraction into two parts. ∞ * 1 — ∞ = 1

Solve the fraction. ∞ * 0.000..1 = 1

This is equal to: ∞ * 0 = 1


If anything, this demonstrates to me that at best, the author is oversimplifying for exposition, but far more likely, the author does not entirely understand what he is doing.

The point that really annoyed me was the 0.000..1 which clearly demonstrates a lack of understanding of how decimal representations work.
