Nice to read you

Not “ No ”, while True as well. Right that it is not the only way to
define it.

You may define the attraction as the opposite of the repulsion, or you
may define the repulsion as the opposite of the attraction. In some
area, you may define Pred and Succ based on “ + ” and “ - ”, or in an
as good way, define + and - based on Pred and Succ.

There are no Pred and Succ on reals, complexes and the likes, but
their “ + ” and “ - ” are not either the same too (homonym, but
different things), and that's because their “ + ” and “ - ” are not
the same that they do not have a Pred and Succ.

This topic is a lot attractive
