Hey man, if you want to resort to some weird appeal to authority argument despite having clear examples against what you are saying - go for it. You can choose to die on that hill if you want to.

I believe you're conflating the rules of maths with the notation we use to represent mathematical concepts. We can choose whatever notation we like to mean anything we like. There is absolutely nothing stopping us from choosing to interpret a+b×c as (a+b)×c rather than a+(b×c). We don't even have to write it like that at all. We could write a,b,c×+. (And sometimes people do write it like that.) Notation is just a way to communicate. It represents the maths, but it is not itself the maths. Some notation is more convenient or more intuitive than others. × before + is a very convenient choice, because it easier to express mathematical truths clearly and concisely - but nevertheless, it is still just a choice.
Obviously more letters would make the mnemonic worse, not better. I was making a joke.
As for the brackets 'the rules around expanding brackets' are only meaningful in the assumed context of our order of operations. For example, if we instead all agreed that addition should be before multiplication, then a×(b+c) would "expand" to a×b+c, because the addition is before multiplication anyway and the brackets do nothing.
I've got a mastodon account. The people I follow don't mark snarky quips. Instead, they post updates of things they are making (music, games, and comics mostly); and they share photos that they've taken, and links and comments to news that they find interesting. Compared to Lemmy, it's more personal, because when you respond you are talking directly to a person that you are likely to talk to again.
Mastodon doesn't use a personalised algorithm. So your home feed will only show hashtags and people that you follow. (There is an 'explore' feed for seeing other stuff that might be 'trending' or whatever.) So if you are seeing too many snarky quips - just unfollow the person making them.
We could study what various apes do, and try to use that to guess at possible human behaviour - or we could literally just look at human behaviour directly. Surely the direct observations of what humans do is going to give us a more accurate and useful model of human behaviour compared to observations of other species.
So then set up dual boot, with default going to Linux, and if you ever find that a game you want to play won't work for whatever reason just boot into Windows to play it. No big deal.
That's basically what it was for me. For many years I've had a folder saved on my computer called "registry tweaks", in which I've maintained a growing list of notes about all the settings and registry edits and other cruft I have to change to make Window less-shit. (Most of it is about the registry, but not all.)
That list of tweaks just kept getting longer; but there was also a growing set of things that were bad and unfixable; (various nags, and surveillance / telemetry etc.) . No one thing was intolerable, but as a whole - it just isn't worth it any more. It's easier to learn to use an entirely new OS than to continue to wrestle with the enshitification of Windows.
I set up Linux dual-boot as well, around half a year ago now. But I made (Mint) Linux the default boot option; so that when I turn on my computer, I get 3 seconds to interrupt it and choose Windows - otherwise it just starts Linux. And just like that, I've never used Windows again. There just hasn't been any need or desire.
If someone is setting up dual-boot with the hope of maybe switching to Linux, I'd say it's import to make the Linux boot option the default. Otherwise they'll still just be booting Windows most of the time out of habit, and never make the switch.
What in particular do you feel like is missing? I mean, there's a lot of stuff on Linux already. There's no shortage of apps or games. But there might be some specific thing that you want that linux doesn't have.
I use RSS a lot too. It's particularly useful for things that update only sporadically, like a personal blog or a slow-running webcomic. The updates show up in the RSS reader, and so you don't have to spend time checking low-traffic sites (or abandon them). You can also use RSS to get updates from youTube channels if you want, without needing an account.
I use theoldreader.com as my RSS reader. But I'm thinking that I might just switch to using Thunderbird instead at some point. I'm happy with theoldreader, but I figure that if Thunderbird works just as well, then that might be better for reducing information leakage. (Which isn't a big deal in this case, but it's just a good general principle to minimise it.)
I do that too... but sometimes its hard to tell which email I should use.
For example, if I create a patreon account to pay people - I'm giving financial info and accessing stuff that I actually care about - which suggests I use my 'real' email address. But on the other hand, the email address is shown to people I'm paying, and I don't necessarily want them contacting me in that way, or even know that that email address exists. As in, I might want to support them - but that doesn't mean I trust them to respect my privacy. So then maybe the spam email address is the way?
The examples I gave were that the expansion of brackets would be done differently if the order of operations was "PESADM"; and I also drew your attention to the fact that reverse polish notation exists, in which there are no brackets at all and the order of operation is entirely determined by the order that operators appear, with no hierarchy of operations. As for your appeal to authority, let me just say that your level of qualification on this topic is not above mine. It adds no weight whatsoever to your argument.
I just glanced at your post history to get a sense of why you were so engaged in this. I was a bit startled to see that you've been on a bit of a posting spree in this thread, which I point out to you is a 3 month old post on a 'memes' channel. I see you've taken issue with a lot of what people have said here. My suggestion to you now is that there probably won't be a lot of engagement in this thread from this point on. So perhaps you should just ponder what is said, and prepare yourself again for next time this comes up. Perhaps you can start by seeing if you can get a consensus amongst fellow experts in a maths channel or something, because at the moment it seems like you're on your own.
