The M & D are interchangeable meaning, you do the operation based on which comes first going from left to right. This is the same with Addition & Subtraction.
What’s the answer?!

I typed into calculator and it automatically rewrites as
6 div (2(1+2))
which would give 1.
6 div (2(1+2))
which would give 1.
I brought that up, perentaces has priority. It gets into more detail when you get older.

The answer is 9...
You start off with the parenthesis - 2+1 = 3
Then you go back to the beginning of the problem and do 6/2 = 3
Then 3*3 = 9.
That's the only solution and the right one.
you always start with whatever parenthesis there are in the problem and then see if you have any multiplications or divisions.
If you have both you start with the first one, and then proceed to the next one. You can't start with whatever you please, there is an order.

Pemdas doesn’t force left to right. Check my post above.
This is what I've been taught in school in first class, and it also makes sense. You can't just solve it however you want, you always work from left to right.
PEDMAS? IT'S BIDMAS last time I checked. The answer is 9, if anyone does not agree go get an education and stop playing minecraft like stupid idiots kms
This is why Americans fail maths more than anyone else in the world yikes.
USING BIDMAS RULE:
B --> Brackets
I --> INDICES
D --> Division
M --> Multiplication
A --> Addition
S --> Subtraction
First step
(2+1) = (3)
Second step
6/2 = 3
Third step
3*3=9

9. First, use parentheses. 1 + 2 = 3. Simple. Skip exponents. Then comes multiplication/division, which is clearly where everyone is having the issues. Neither of them come first, BUT, it is ordered from left to right. As 6/2 comes before the (1+2) which is now (3), so 6/2 is 3, 3(3) is 9.[DOUBLEPOST=1549394902][/DOUBLEPOST]
dunno if this is a joke, but p means parentheses (aka brackets) and e means exponents (aka indices)

You don’t have to work left to right. It just makes it easier for younger kids, Ask any of your math teachers.
If a scientific calculator says 1,
it's probs 1,
however, I feel if this was "real world" or an actual equation not meant to confuse people, it would be written differently.
I kept getting 9 tho, myself, but calculators don't lie. I still don't understand why the cal adds in extra ().

That's quite interesting. After reading that, I agree that it is mostly psychological and the intent of the expression isn't clear enough. This shows why everything becomes fractions instead of using the division sign at a certain point in math education.
Sorry, but your grandfather is incorrect, and please don't quote his certified math stuff because I'd fire back.
The correct answer is 9. If you'd like further explanation on this please let me know.
This sounds more of a regional problem more than a math problem to me -
Americans are taught our own math - we use inches, feet, yards, and miles and we're taught PEMDAS
From what I can take, majority use the metric system - nanometer, millimeter, centimeter, meter, kilometer and are taught BIMDAS or BIDMAS whatever.
