"6 / 2(1+2)" is just a shitty way of writing "6 divided by 2(1+2)".
No, it's a shitty way of writing (6 / 2) * (1 + 2) because it makes people think it's 6 / (2(1+2))!
Like, my first reaction was also to interpret it as being 1, because it's designed to confuse. But that doesn't make the wrong interpretation correct, it just illustrates that our brains take certain shortcuts that aren't always correct.
I think we ought to introduce intuitive calculation to the larger world
All memetic math fights start with something that Feels Right and something that is actually right.
(though in this case "actually right" is completely arbitrary. There is no "truth" to mathematical notation. This distinguishes it from e.g. Monty Hall, where the objective answer (2/3rds car) feels so much wronger than the incorrect answer (1/2 car))
By the way, the Monty Hall problem gives you a 50% chance regardless of your choice because all other variables no longer matter at the point of decision.

I find montehall to be way more understandable if you change it from 3 doors to 100 doors, and go: Choose 1 door of 100. Now we open up 98 wrong ones.
2 are left, do you switch?
I find explaining that to people is way easier.
That said, I get why 2/3 car works (I'm mentally parsing it as: you had 1/3 shot of choosing right to start, so when you're given the swap option, since there are only 2 options, and your choice had a 1/3 chance of being right, the other option must be 2/3 chance of being right), but it is weird.

I will never PEMDAS
This has Acorn written all over it
For that price, sure.
Yes, that's the good recent one
Very much so. Its a good game.
Yes.
Yes
x = 3
y = 2x
y = 6
z = 6 / 2(1+2)
z = 6 / y
z = 1
In the case of Subsitution vs Order of Operations, the court isn't happy.
This is the proper order of operands:
The "viral problem" is written in a shitty way, in order to make it viral.
The Court should kick it back to the lower Court and get the Plaintiff to write it unambiguously.
3 * 1+2 does not equal 9 just because the 1 and 2 have no spaces between them!
Exclamations!!

My post was public. I woke up to 200 comments worth of randos arguing.
But the only important question is the one they never ask: Are you white?

It’s just a badly written problem
Idk do you like filing W-2s and giving workplace conduct seminars?

I'd start with the first Theorem before I moved onto the sequels to avoid spoilers.
but they're listening to every word I say
Not sure if... serious....
There are 100 doors, with one prize and 99 chainsaw murderhobos. Pick a door.
OK, you picked door X. Now, let me open 98 of the other doors, to reveal 98 chainsaw murderhobos!
Would you like to switch to the last unknown door?
Mathematicians: agreed.
Math undergraduates everywhere: You can do that?!
I find montehall to be way more understandable if you change it from 3 doors to 100 doors, and go: Choose 1 door of 100. Now we open up 98 wrong ones.

Does still feel bad when you switch and it's like
"Actually, this was the 1% of timelines where you picked correctly at the outset! Sorry, little Jimmy. Try not to splatter too much on set."
