48÷2(9+3) = ???

Distribution = Multiplication. You are multiplying the inside numbers by the outside.
If you are doing this, you have to do division first.
48 divided by 2 is 24.
Then distribute that to the numbers inside
24(9+3) in which 9+3 would already be found to be 12.
That is the proper way to do it, and if you don't know what, then I don't know what to say.
Distributive Property works, but you still have to follow the order of operations.

I will admit if the equation is a fraction, the answer would be 2. But as is? 288.

Exactly. Clearly the author knows how to use parenthesis, if they wanted to indicate THAT fraction all they had to do is add a parenthesis before the 2 and after the end parenthesis.

division problems are fractions, so im not sure as to how you think it changes. you're solving a multiplication problem by multiplying 48 halves and (9+3) when it clearly says to divide 48 by 2(9+3).

the division sign is the only sign in the problem, so im not sure why yall don't set it up as a classic division problem.
No. The only thing that is being divided is 48 by 2. If it was 2(9+3) it would all have to be contained within parentheses or brackets. This is basic in algebra.
You can't just assume that. It is not one term. I don't know what to tell you.

that's what I'm thinking too.

The answer is clearly 288, there's no other way around it.

You learned it wrong.

You are implying that juxtaposition overrides order of operation like I said show me a math problem that proves this.

in a division problem you have a÷b in a multiplication problem you have a*b. you're implying a multiplication when there's already a division sign. don't make it harder than it is

a= 48
b= 2(9+3)
so your saying 1/4*3 is really 1 over 4 times 3? proof to support this claim? Your essentially saying that the division symbol ALWAYS indicates a fraction which is not true at all. If that would be the case why even have the horizontal line for a fraction?

What are you talking about. I distributed the 2 to the 2 and 3. how about this to make it easier

So now distribution goes before solving whats in the parenthesis?

You do realize the horizontal line clearly adds parenthesis on terms? With the horizontal line it is (1)/(4) just like if you were going to do this problem it would be (48)/(2(9+3))

I am not sure if you know that when you see communitive property with multiplication it always means distribution. The only time that isn't the case is if it is division inside the parenthesis or multiplication.

It does not matter the order (in this particular problem that has both communitive and distributive properties) I solve the problem it only matters that the answer is correct which I proved to you.

horizontal lines for fractions are division tho. the fraction of 1/4 is 1 divided by 4.

I already explained this:
Because if it's a fraction, you solve both different ways.
Fraction: solve denominator first, divide by numerator.
As is: Order of operations, parentheses, exponents, multiplication/division (whichever comes first from left to right), addition/subtraction (whichever comes first from left to right) in that order.
Solving the equation any other way would just be completely ignoring the rules altogether and just making up your own.
