I said (and you snipped):

You are making no sense.

And you have forgotten that you claim Cantor uses multiplication
on reals which are not also cardinals.

Does 3.14159... appear in Cantor's number-classes, then?

As I said before, and you have deleted:

"And what does this give? an ordered set; but no multiplication
defined here, of course! "

Still not a single example of Cantor multiplying a transfinite
number with anything other than another ordinal/cardinal.
