Hello Michiel,

 MvdV>>> By order of operation:  (7/7)/(7x7)=1/49

 MvdV>>> or:                     (7/(7/7))x7=(7/1)x7=49

 NB>> Ah, you're one of those people. :)

 MvdV> Yes, I am.

I am not so sure.

 NB>> Multiplication and division are on the same level in the order of
 NB>> operation (PEMDAS):

 NB>> 1) Parenthesis
 NB>> 2) Exponents
 NB>> 3) Multiplication AND Division
 NB>> 4) Addition AND Subtraction

 MvdV> Not according to the rules I was thaught.

What rules might those be? Those taught by the Romans? Or the Greeks?
We both know that nobody wrote the rules. We all make them up as time
goes by. Sometimes they work. Sometimes they don't. And that is how we
learn. By trial and error.

 MvdV> MVDWOP (Meneer Van Dalen Wacht Op Antwoord)

 MvdV> Machtsverheffen, Vermenigvuldigen, Delen, Worteltrekken, Optellen,
 MvdV> Aftrekken.

 MvdV> Multiplication goes BEFORE division.

PEMDAS is unclear on the subject, as it states multiplication and
division rather than multiplication before division. But it does
follow with the phrase (from left to right) and then addition and
subtraction (from left to right).

 NB>> No need to make it harder than it is, and also no need to add anything
 NB>> to it. Just do it from left to right.

 MvdV> Not according to the rules I was thaught.

So who made the rules? Can you tell me? Whatever rules they might be,
you should know. But that is the way of the world. We just accept the
rules. Whatever those rules might be. Without question. Kind of like
cicumcision. Snip snip! All done!

 MvdV> So the rules are different in different parts of the world.

Different rules for different folks. One set for Romans. Another
set for Greeks. And let's not forget about the set for the Chinese.

 MvdV> Thanks for parenthesis.

Nobody made the rules. Whatever "rules" that do exist are only
versions of what others think they should be. For example -

6 ö 2 (1 + 2) = ?

The order of operations are only what you want them to be,
depending on your moment in time. If you use the current rules
that you are most familiar with the "correct" answer is 9. But
if you use the rules as they were prior to 1917 the "correct"
answer is 1. So which is it? Or is either of those answers
correct?

For Life,
Lee
