>Yes. Nobody has denied that. But since oo is no natural number you have not a sum over terms with natural indices but the limit.

Again, oo is a shorthand for the limit and the infinite sum is defiend as the limit.

>The last does not follow. Correct is: The limit of the infinite sum of rationals is irrational.

Which is the definition of an infinite sum you moron.

>If there are already *all* finite numbers of nines then your claim is wrong. More than all is not possible.

More than any finite number.

>It does not. Logic clearly states: If all infinitely many terms fail, then all infinitely many terms fail. This is even simplest kind of logic: a tautology.

Yes but infinitely many terms does not fail.

>Difficult to understand? Or only difficult to answer?

Asking for clearification for what you are exactly asking for.
