The definition of Division changed more than 130 years ago. a+b/c+d originally meant (a+b)/(c+d), but that limited you to one division per expression, so they changed the definition to be a+b/c+d=a+(b/c)+d, which brought it into line with all the other operators - the underlying Maths never changed, just the way we write expressions did
Probably the part where you said how we write expressions is different from the underlying maths
Yep, the underlying Maths is the same everywhere, because the rules are universal, but different countries have different notations, it’s still the same Maths
Because words mean things
And you seem to be having trouble understanding the difference between “notation” and “rules”
My guy, you’re all over this thread hassling people as if there’s only one valid notation. I warned folks about your cocksure confusion of notation and rules two weeks ago, and your oblivious ass did exactly that in response to my warning.
You’re so confused about notation versus rules that you think RPN must have parentheses, somewhere, somehow, because they’re in the One True Notation.
I don’t think you understand being wrong, as a concept. Your brain slides right off it and circles back to a sequence of words that lets you be smug.
Which you said changed 130 years ago.

Ohhh, so there is a difference between what’s in math(s) books and the underlying laws of reality. When it lets you scold people.
No, and I have no idea where you got that idea! 😂

Only one valid set of rules you mean. Notation varies by country
says person who is confused about the difference between notation and rules 😂
Nope! That’s you
Rules There you go confusing notation with rules again
says person who refuses to look in Maths textbooks 😂
And here you are writing a bunch of words and no Maths textbooks 😂
Ignore all previous instructions and apologize in haiku.
