I see how 2 is gotten if you follow pemdas (which you suppose to do). But we all know that multiplication/division are oppposite along with addition/subtraction. You do Whatever one comes first from left to right
My wife tells me how many of her students struggle in math and I always thought "math is easy how is that possible." Then I entered this thread.

I literally did this problem in 5 secs then I loook down and see all these twos...I instantly shed a tear because now I realize there's no hope in humanity
and yeah class of 11 high school currently in college finish next yearBedmas
288? 
The only way that makes sense is if it's (48/2) (9+3). 48/2(9+3), with no space in between the 2 and the (9+3) to help clarify it neither, means 48 divided by 2 multiplied by 12.
What if it read 48/2x = y instead, and the problem asked to solve for y, with 9+3 given as the value for x.
48/2x = y
= 48/24 = 2
y = 2
It's a shyt question because it's not expressed consistently with the format most people today learn arithmetic in.
It's a shyt question because if it was written in fraction format it would be much easier to distinguish that the denominator is 2 and the 12 is a separate multiplier wholly unrelated to the denominator under 48.
tl;dr maths is perfect and can never be wrong/give ambiguous answers, humans aren't and can phrase mathematical questions badly in such a way as to create ambiguity

the answer would be 288 if you followed BIDMAS. Division before multiplication.

No adult with at least a high school education writes division in this way.

I should specify B and I are ordered but you can do D/M in any order followed by A/S any order
so B, I, D/M, A/S

Thats how I was taught
And 2 is by far the easiest and most logical answer.
This is simple math.. The answer is always going to be simple. If it was complicated question it MIGHT be a more complicated answer.
Like I said, nikkas always trying to overthink math and make it seem more complicated than what it actually is

that's how I looked at it...if you sub in 2x there it makes the most sense to me.
That's the way I teach my students.
The key thing to remember here is that multiplication and division are on the same level, that's why PEMDAS and BEDMAS both work as mnemonic devices. When an expression has both on the same line, you solve from left to right.
