2+2=4 is not an authoritative statement. It follows logically from the structure of Allegra and from the experience of reality in your life. No one tells you that this is true, it is self evident. Anyone saying that 2+2=5 is attempting authoritative control of your mind.

No. That's not actually true. And that's not what is happening here. What is happening is that it is being pointed out that due to the imprecise nature of reality, as opposed to the fantasy of pure logic, sometimes 2 + 2 = 5.

In the context of algebra and in the context of reality, 2+2 always equals 4. You are gaslighting yourself.

Sure, but in the context of algebra 4 sometimes equals 0 (in Z/2Z), or 2 or -1 (in Z/3Z) or -3 (in Z/7Z). It's also 2+2, but I can write 2+2=-3 and be correct in one context.

That's literally algebra.

I gotta say the pure cringe levels here are really getting me off, and that's the only reason I keep replying Like maximum Dunning-Kruger

He likes to recycle the Dunning-Kruger argument. He tried that one on me earlier while attempting to argue that rounding can prove || plus || equals |||||

It's not an "argument", it's me making fun of you How often do we have to go over this

In this case, your friend Stuart accused someone of having obviously flunked high school algebra for invoking the concept of an algebraic ring This is a very embarrassing thing for him to do, and I am now laughing at both him and you

Like we do not need to teach HS kids ring theory, but we can teach them matrix algebra to point out that some things which are true in more familiar contexts are not true in others. Like a*b=0 => a=0 or b=0 is true in Z, Q, R, and C but not for any ring of nxn matrices n>1.
