Uhm - no, it’s ambiguous. The order of the evaluation can be one of two ways depending on operator precedence. We’ve gotten two possible interpretations - that ALONE should be an indication that it’s ambiguous.

If it were written correctly - parens would have been used to disambiguate the results to guarantee a single possible interpretation.

My crazy college prof said to write down an approximate answer by looking at the problem....Then solve it.

He was a great teacher. No calculator...he did allow slide rules...and this was about 1980.

48÷2(9+3)

#1 the () is the priority..
#2 next would be the other equation (48/2)..
#3 the () is multiplied times the answer of #2
#4 288

Using standard left-to-right decoding, the answer is 288.

(I had to check my memory that left-to-right is the RULE, as opposed to a preferred method, BTW)

The correct answer, with standard mathematical notation, is 2.

That is correct, because perenthesis supercede multiplication and division.

Would that ALL our problems were this easy!!
AND people RESPECTED the RULES (constitution).

Which “sign” takes precedence? ie do you use FIRST?

The RULE says “divided by”.
That’s IT.
The answer is

2

Casio fx-115n says it’s 288. And I guess there’s no news to talk about today?
