Hi Sekky,
Welcome to the forum!
Thanks for the post!
I do agree, the symbol you have given is used to denote 'does not belong to'. But the one I had given is also used.
Thanks again.

No, it isn't, it's used to denote containment, not lack thereof. It's simply back to front, equally as every single other binary relation can be written back to front, as in subset containment or have you ever heard of < and >? The symbol means the same, but the relation is reflexed.

The flaw is you assume P(n) -> P(n+1), which is the proof requisite. It's circular

Not many stupids pique my interest as much as you do, but I'll just go right ahead with one of my more intimate authorblues' quotes

YOU ARE A *#!&# IDIOT!

You are seriously attempting to tell me that there is a actual distinct difference between (1/3 * 3) and 1/3 * 3? You are seriously trying to say that!? What planet are you from!? Have fun working in McDonalds, you claxon.

Prey then tell me, what is the difference between (1/3 * 3) and ((1/3 * 3))? If you're so adamant that parenthesis changes the outcome (which it doesn't you stupid child), then there must be a clear cut difference between those two expressions.
