What you just said is at best irrelevant and at worst meaningless. No, the fact that multiplication is defined in terms of addition does not mean that it is required or natural to evaluate multiplication before addition when parsing a mathematical expression. The latter is a purely syntactic convention. It is arbitrary. It isn’t “accounting.”
It is, in fact, completely arbitrary. There is no reason why we should read 1+2*3 as 1 + (2*3) instead of (1 + 2) * 3 except that it is conventional and having a convention facilitates communication. No, it has nothing to do with set theory or mathematical foundations. It is literally just a notational convention, and not the only one that is still currently used.
Edit: I literally have an MSc in math, but good to see Lemmy is just as much on board with the Dunning-Kruger effect as Reddit.
The difference between 0.999… and 1 is 0.
It is possible to define a number system in which there are numbers infinitesimally less than 1, i.e. they are greater than every real number less than 1 (but are not equal to 1). But this has nothing to do with the standard definition of the expression “0.999…,” which is defined as the limit of the sequence (0, 0.9, 0.99, 0.999, …) and hence exactly equal to 1.
Put another way, given the size of Meta and its userbase, it’s completely infeasible for a typical instance to moderate on their behalf, so defederating due to insufficient moderation makes sense. Just like with Beehaw and sh.itjust.works or whatever. (I take for granted that moderation will suck ass because gestures vaguely at Facebook.)
That’s a good enough reason for me. I also think federating with Meta is a bad idea on principle and out of self-interest, since they will extinguish the fediverse at the first possible opportunity and federating with them gives them the chance to draw in users and later wall them off.
