Your mindless and irresponsible claims about Norm
Megill's system is another example.

If you want to debate that system, it would help to start a new
thread. He uses an expression like xRy(Rz)=(xRy)Rz and substitutes +
for R but there is nothing at that point about + or - so - could
equally well be substituted for R.

Silly boy, there is an hypothesis of that theorem that you have not
shown is satisfied by subtraction. That has been pointed out to you
already by a few other posters.

See, I repeat, you have not shown that subtraction satisfies the
hypotheses.

What hypotheses? You have given no hypotheses.

C-B

There is also the general question of what ZFC alone can prove and
what he says regarding that question and what his site shows.
You don't know what ZFC is.
Published papers don't even agree as to what ZFC is. But I know
exactly what it is. What is it? Then I'll say. It has to do with
Computationally Based Logics.

There are various formulations of formal ZFC, but they are not so
dissimlar that a general definition can't be given. And what you know
exactly is what you BELIEVE ZFC to be. From your postings in the
thread that discussed ZFC proving general results in mathematics, it's
clear that you don't know what ZFC is.
