"Upon reading Crowley one frequently comes across his references to the 0=2 forumula? What is the significance of this, or more to the point, what exactly is the 0=2 forumula?"
The gist of it is this:
There is no such thing as the number 1. "Unity" can't mean "One-ity" because there is no such thing. If you reduce all of the universe to 1, and are perceiving it, then there are two: you and the universe. On the other hand, if you reduce all of the universe to 1 and don't stand as witness to it, then there are, in fact, none - there is nothing to count. Nothing is differentiated from everything else, therefore there is nothing.
Nuit, therefore, stated that she should be known as Two and None.
Years before receiving Liber Legis, Crowley worked this out as his solution to the philosophical problem of Creation. Every creation myth had a causative factor or source, the origin of which was ultimately left unexplained. The pre-adept philosopher Aleister Crowley solved this problem by saying that the Universe came, in fact, from nothing at all. There was no prior thing to explain. But then Nothing expressed itself as Two (again, Nuit claims this process as Her own), starting the creation process.
Very ovarian, I think, and would have made Elohim blush.
