1) Is 3333.. to n places a natural number for all n? Yes or no please. You use the term "infinite" to describe the sequence of 3's in .333333..... 2) What is your definition of infinite? 3) What is your question?

Math Team Joined: Dec 2013 From: Colombia Posts: 7,660 Thanks: 2635 Math Focus: Mainly analysis and algebra  Do you not know what a question looks like then? There are loads of questions directed at you, mostly from skipjack. I have asked some questions and given mathematical demonstrations as to why your ideas are incorrect which you have made no attempt to refute. I answered this earlier today. But the answer doesn't mean what you want it to, because of your misunderstanding of the term "for all $n$". Your question is rendered imprecise by your usage of "for all $n$". I have given precise mathematical definitions of finite and infinite in terms of sets and sequences. It's easy to formulate a similar definition for decimals, but I'm not going to waste my effort doing it here. Informally, you may take it as a synonym for "nonterminating". Your suggestion that skipjack and I have been vague and ambiguous shows that you don't understand the posts. Rather than writing them off, you should seek clarification. The reason you don't do that is because you know that they show your own ideas to be worthless nonsense. Last edited by skipjack; June 4th, 2016 at 09:53 PM.

Is 3333.. to n places a natural number for ALL n? Quote:
Thanks A finite set of natural numbers has an upper bound. The set of all natural numbers, though consisting only of finite numbers, has no upper bound, and is countable, just like 333...to n places is a natural number for all n. So you are relying on your past definition of infinite, nonfinite and noncountably infinite? A cow is infinite.

However, the infinite (nonterminating) sequence of 3s 333... is not a natural number as I demonstrated previously. Quote:

Global Moderator Joined: Dec 2006 Posts: 20,644 Thanks: 2084  I have asked you specific questions in your other threads. In this thread, I have drawn your attention to specific flaws in your posts, but not asked you questions. Yes, for each n, but each natural number is finite, so 3333... (nonterminating) isn't a natural number and there is no natural number n that gives how many digits 3333... has. Hence it doesn't follow that the reals are countable.
