Ärende: order of operations
===========================
Hello Michiel,

 BF>>>    There is no other *real* set of rules.

 ml>> apparently there is...

 MvdV> When you run a red light, ist does not mean there is an alternate set of
 MvdV> ruels that says "red means drive on".

And if the light is broken, or the electricity is out?

 ml>>  just like standards, there's several to choose  from ;)

 MvdV> No, you can choose between following the rule or go against the rule.

Rules are made to be broken.  Knowing when to break those rules
and when not to is what we should be discerning.

 ml>>> for example, on a simple calculator this is the answer returned

 MvdV> Then you are not using the calculator in the proper way for that mode.
The
 MvdV> proper way is to it just as one would do on paper.

Not necessarily.  All mathematics is based on addition.
Mathematics is the language of arithmetic, not the operation.

I use an abacus, which is a type of manual calculator.
When using a Japanese abacus, I calculate one way.
When using a Chinese abacus, I calculate another way.
The Romans used a different kind of abacus which had
no beads on top or bottom as each row of beads were
on a single string.

Here is a math puzzle for you.  The Book of Revelation
tells about a number that can be calculated, that number
being 666.

Let him who has wisdom calculate the number of the Beast,
for it is a number that stands for [a] man.

How do you "calculate" a number?  With an abacus!
