Subj : Math Test To : Nicholas Boel From : Lee Lofaso Date : Sun Jun 30 2024 02:56 pm Hello Nicholas, [..] NB> Still no parenthesis needed. Knowing the order of operations, one knows to NB> do division before subtraction. However, if #1 was written like this, it NB> would have a different result because parenthesis goes before division, NB> which I'm sure you understand - being an old school mathematician and all: NB> (7 - 7) / 7 = 0 The order of operations changes over time. NB> Whether it be PEMDAS, BEDMAS, BOMDAS, whatever abbreviation Michiel used, NB> and whatever else is out there, they're all just acronyms for the "order of NB> operations", which never changes. Please. Don't make me laugh. Who wrote the rules? Nobody. As I tried to explain to Michiel (he is very dense) not everything is the same. I even showed him an example to make my point very clear - 6 ö 2 (1 + 2) = ? Go ahead. Solve the problem yourself. It is not that hard. The correct answer is 9. Or is it? Prior to 1917, the correct answer is 1. So which answer is correct? Since nobody wrote the rules, it is whatever goes. NB> From what I've noticed, some countries call parenthesis brackets (I don't NB> know why), where we call "[]" brackets. So the acronym changes to fit NB> whatever country and however they learned the order of operations. Rules? There are no rules. So what does it matter? The rules of order are whatever one wants to make them out to be. And from whatever time. NB> Either way, the actual "order of operations" stays the same. According to who? The Romans? The Greeks? What about the Chinese? NB> Maybe the world shouldn't have made up different acronyms for it - as that NB> obviously led to a lot of confusion, but there's nothing we can do about NB> the past, except to try to stay on the right track in the future. The rules of order are an approximation, made at different times, and even acronyms differing depending on time of usage. So what is the right track? What is the left track? Is there any track one can ever be sure to be on?
