This doesn't answer my question, if my guesses were even correct.

Exactly how they are written in your top/down methodology, just on one line :)

1) 7 - 7 / 7 = 6
2) 7 / 7 - 7 = -6

Still no parenthesis needed. Knowing the order of operations, one knows to do 
division before subtraction. However, if #1 was written like this, it would 
have a different result because parenthesis goes before division, which I'm 
sure you understand - being an old school mathematician and all:

(7 - 7) / 7 = 0

Whether it be PEMDAS, BEDMAS, BOMDAS, whatever abbreviation Michiel used, and 
whatever else is out there, they're all just acronyms for the "order of 
operations", which never changes.

From what I've noticed, some countries call parenthesis brackets (I don't know 
why), where we call "[]" brackets. So the acronym changes to fit whatever 
country and however they learned the order of operations.

Either way, the actual "order of operations" stays the same. Maybe the world 
shouldn't have made up different acronyms for it - as that obviously led to a 
lot of confusion, but there's nothing we can do about the past, except to try 
to stay on the right track in the future.
