Which you said changed 130 years ago

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

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.

    Probably the part where you said how we write expressions is different from the underlying maths.
    
    Because words mean things.

    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

    And you seem to be having trouble understanding the difference between notation and rules
