Not to sound arrogant, but it's a pretty established fact that 0.999.. equals 1.


I think we're using the word "fact" wrong if it is contested.  In pretty much any math equation you will ever come by, it will equal 1.  However, it is not a fact that .999... itself is actually 1.  Every time I see someone trying to prove it, it keeps showing me that they are either using circular logic, or are approximating, then claiming they are the same thing.
