He just proved you wrong. So did I.

Tach, you've been warned by the mods before about 'declaring/prejudicing' and otherwise misconstruing the discussion 'result' even before the discussion is complete.

I pointed out where in my observation his 'proof' is of the trival kind based on convention/definition, not on the fundamentality involved which bring into question those very same conventions/definitions which tend to build up and 'hide' the fundamentalities involved at its most basic level to begin with before the abstractions and trivial manipulations set in.

So please stop trying to 'control' and 'prejudice' the discourse conclusions by 'declaring victory' and/or 'declaring proven' etc before the discussion is complete. Thanks.

This is the **definition** of a multiplication by 10 of a periodic number. They teach that in high school:

10*0.(N)=N.(N) for ANY N.

Your "suggestion" is contradicted by basic arithmetic.

Basic arithmetic books contradict your (fringe/incorrect) claims, 10*0.(N)=N.(N) for ANY N.

Yes, by DEFINITION according to axioms being brought into question NOW. So a definition is not an 'operation' which is more fundamantal than the axiomatic assumption/definition you present as the trivial 'proof' for something that is yet to be decided in THIS discussion.

Again, that is an assertion from axioms/trivial manipulation of symbols and numbers in mixed context (as already explained by QQ).

So please stop with your trivial repetition of axiomatic trivialities as 'proofs' etc. The discussion has not yet completed, and those trivial 'proofs' and 'axioms' etc are what is being brought into question IN this discussion. So no more circuitous and self-referencing 'rote-learned' retorts that mean nothing in the context we are discussing those things in. Thanks.

Undefined espouses a lot of fringe misconceptions (such as "zero is not a number", "0.999... is not a number"), etc. I just shown his newest claim to be false, exactly as his other claims. So did Pete.

Without giving the full context and understandings/arguments brought in support of those comments I made elsewhere, you are TROLLING and making obviously personal disparagements based on YOUR own misconstruings out of full and proper contexts.

Please STOP trolling and personalizing this thread/discussion, Tach. Else I will have no option but to report you for it. Thanks.
