Hey guys, brainlet here:

So I'm taking my proofs/ logic/ sets class this semester. I think - brainlet although I may be - I may have stumbled upon an entirely overlooked quirk of logic that may prove to destroy the very foundations of mathematics (and quite possibly reality).

So recall x ≥ y ≡ (x > y) v (x = y)
... and by """definition,""" that's the 'inclusive or,' mind you. So essentially the statement above reads "x is greater than or equal to y is identical to saying x is greater than y, x is equal to y, or both x is greater than y and equal to y." Which is obviously false. A number cannot be greater than AND equal to another number. The logical notation should be the 'xor' symbol, but I suppose """mathematicians""" allow greater flexibility for their useless masteurbation by ignoring this obvious quirk and using the 'inclusive or.' How/ why is this overlooked?

>pic-related is related because it's mfw the entire universe of mathematics destroys itself today because I shitposted this proverbial ton of dynamite onto the mathematics section of this obscure Norwegian kite-flying forum

See you faggots in hell.
