common notions in common notation,
what he read is not what I wrote,
not even if I wrote it a hundred times.
So, now I try to find uncommon ways to write them.
Yes, I understand your motivation (I think),
but -I'm sorry to say so-
I don't think that you will succeeed. :-)
Ah, but it is the journey not the destination.

However, deleting context courts confusion,
as you have noticed.
That's why I tend to use (i.e. stick to)
standard notation and common notions
(in this context). :-)
Since you find that that works for you,
I would not dream of asking you to do otherwise.
My impression of WM is he is someone who
thinks that they know what these common notions are,
and who doesn't know.
Yes, completely agree with you.

Try to remove all natural numbers individually from ℕ.

Wie stellst Du Dir das vor? Muss man sie in Mückenhausen einzeln von
Hand removen? Das kann in der Praxis [->kein Supertask] lange dauern!
Ich hätte einen Alternativvorschlag: Man kann das mithilfe der "großen Differenz" (\\) so hinschreiben:
IN \ {1} \ {2} \ {3} \ ... = IN \\ {{1}, {2}, {3}, ...}
Ist das nicht "individuell" genug? (Wir wollen hier Linksklammerung voraussetzen, um keine unnötigen Klammern schreiben zu müssen.)
Es ergibt sich dann natürlich das "erwartete" Ergebnis: {}.

WM explained :
Yes. But every n ∈ ℕ_def has ℵ₀ successors which never vanish by
counting. They can be removed only collectively such that nothing >>>>>>> of ℕ remains.
Wrong,
Try to remove all natural numbers individually from ℕ. Fail.
Because you cannot remove them -- *SETS DO NOT CHANGE*.
But the result of subtraction can be calculated. That is understood
by removing.
That is not quite the same as constructing a difference set.
It is precisely the same. And if you disagree replace "removing" by "constructing a difference set".

You can remove what is removable individually.

Individually means you can name the individuals,
