I know it’s not a rule, hence why I put it in quotation marks. I noted in another comment that, yes, the proper way is to group it as 1+(-2)+3 and you can do it in any order. What I meant with ““rule”” is the meme questions pray on people not understanding/remembering what the actual rules are or why “left to right” conventions exist.

And you showed that you were one of them. Every answer you got other than 4 was wrong, because you didn’t understand the rules. spoiler alert: doing it in different orders never means add brackets to it. Addition first for 10-1+1 is 10+1-1, not 10-(1+1). See previous textbook example
why “left to right” conventions exist
They exist because people like you make mistakes when you try to do it in a different order. Either learn how the rules work or stop spreading disinformation. Well, you should stop spreading disinformation regardless.

No it isn’t.
You can do it in any order anyway
left to right 1-2+3=-1+3=2
addition first 1+3-2=4-2=2
subtraction first -2+1+3=-1+3=2
right to left 3-2+1=1+1=2
