I asked about the real number 0.777... quite explicitly. 0.7777... has only one meaning that I know of.
All the worse for the students! They do not recognize incompetence when they see it.

There is no lie. This "agreement" has no obvious meaning, other than "if we agree that 0.777... is a terminating decimal, then 0.77... terminates."

I am not familiar with the text, but I know that you are literally incapable of distinguishing valid argument from invalid or, indeed, the most basic sort of mathematical reasoning. Honestly, the results of this conversation are sufficient to show that. -- Jesse F. Hughes "How come there's still apes running around loose and there are humans?
