PEMDAS and BODMAS

[johnnyoff625]

Can you please help settle and ongoing argument between members of a group i am in. There seem to be Two camps.: those who pick "b" and those who insist the answer is "c"
This problem may seem very elementary... But it brought up all kinds of references to PEMDA and BODMAS

Ok...
All the "A's" are wrong
All the "D"'s are wrong
Its either "B" or "C" depending on whether you add or subtract at the end of the equation:
3-3×0+3÷3=
3-0+1...
(can we all agree on that?)
Doing Muliplication THEN Division,
yields 3×0=0 and 3÷3=1 bring us to
3-0+1...
OR if you prefer, the BODMAS way, DIVIDE first
3÷3=1 and. THEN MULTIPLY 3×0=0,
Again yielding 3-0+1
So far, so good, either way it's 3-0+1
But then there SEEM to be two approaches:
If you say 3-0=3, and 3+1=4
You'll get 4...BUT
If you say 0+1=1, and 3-1=2
You'll get 2
BUT...Don't BOTH PEMDAS and BODMAS
say "A.S." at the end of the acronym?
So, doing the "ADDITION" FIRST...0+1=1,
and THEN the SUBTRACTION,
YOU GET 3-1=2

so i would say the "2's"
(or, the "B's") have it.
Just sayin....- lol?
my thoughts:

The purpose of writing down a calculation is usually to communicate to someone a calculation that you want performed. Obviously you want the person to do the calculation that you intend. The best way to try to avoid ambiguity is to put in brackets to express what calculation you want them to perform.

Additionally, I note the following description of the PEMDAS/BODMAS convention, which appears in another such discussion thread:

If you say 0+1=1, and 3-1=2

Can you clarify where the negative sign comes from?

The MD or DM stands for multiplication OR division whichever comes first from left to right..
The AS means Addition OR subtraction whichever comes first from left to right.
The answer is (C) 4. It is not open to debate.
