288.

48/2 * (9+3)

9+3 is first, which is obviously 12.

Then you get:

48/2 * 12

48/2 is first, because when the order has only Multiplication or Division (or Subtraction and Addition), you just go from the left.

So now:

24 * 12.

Which = 288.

But you're supposed to eliminate the bracket by multiplying it with what is directly beside it outside the bracket.

2(9+3)=24 not 2x12.

I spent 5 minutes looking at it and getting both answers.

Then, this is the only thing I could think of:

lol Division and Multiplication don't take precedence over the other. Some learned BEDMAS (Brackets exponents division multiplication addition subtractions), others learned PEMDAS (Paranthesis, exponents, Multiplication, division, addition, subtraction).

I got 2, but now am Confused... is going left to right actually a rule in the case of Multiplication and division? Never heard that before.

no he's not. The brackets only apply when there's an equation in it

once the 9+3 is solved the equation becomes:

48 / 2 * 12

going left to right the answer is 288, not 2

I'm wondering if 2*12 and 2(12) are considered the same.

Either way, it's a ******** question and just plain sloppy for no reason.

The problem with how it's written online annoys me.

In reality, you use fractions for divisions unless you're in grade 3. Once you use a fraction it would be easily noticeable if the (12) is on top or on bottom.

The reason you're getting 288 is because you're not solving the brackets properly.

You solve a bracket my multiplying what's in it right away with the number beside it.

Example:

2(4) would switch to 8...not 2*4. In the first step, you're supposed to eliminate that 4 by multiplying it.

Therefore 2(9+3) doesn't switch to 2*12...but to 24.

In this equation,the 2 is connected to the 3 and 9 right off the bat, but not the 24 at the start.
I just did it on my GRAPHIC calculator. Gives me 288.

The answer is 2.

24÷2(9+3)

Work to get rid of brackets first...making it

24÷12

Making the answer

2

Try it on your own calculator.
It says there's an error and wants to add a multiplication sign between 2 and the opening bracket. When I click on OK, it answers 288, which is the correct answer.
