Would someone check the attached file? It's simple high school algebra.

I just read the very first few lines, as it seems to be one more simple ""proof"" of Fermat's last Theorem or something of

the kind. The language used is sloppy, and where it begins with that nonsense of
$$\text{if}\,\,A+B=C+D\,\,\text{and}\,\,A=C\,\,,\, \text{then} \,\,B=D$$
which is so boringly obvious that it shouldn't even appear in a paper trying to prove "a very important theorem of mathematics"

"Bully"? Were you expecting me, or anyone else, to write your opinion on this, or you'd rather have my own opinion?

Well, perhaps other members of the forum have different opinions. Good luck with that.

DonAntonio: I can't find where he says what you say he says. Can you please point out the page and the phrase that was used?

Hi manuelsmarin and welcome to the forums.

Can you please explain in more detail step [8] of the general proof for n > 2? I get all the identities including step 9 used for later steps (i.e. 10 and greater) but not that one. What assumptions have you made?

IF $(x-y+z)=(u+w)$ AND either $(x-y)=u$ or $(x-y)=w$, THEN, in the first case, $z=w$ or, in the second case, $z=u$.
