Well, um, yeah. That's where you went wrong. How did you get 8.1?

What do you mean? When I multiply .9r by 10, I get .9almostr or .9r with one less decimal place? I think that inifinity minus any non-infinite number is still infinity. Especially one, since one is so... oneish. This is when you get into those freaky
(*cough* obsessive *cough*) metaphysical debates over the nature of infinity.
