I've seen some of the threads with 2 as the answer coming from teachers.

its because a lot of people were taught brackets then multiply (which is implied by the number 2 being next to the brackets) then divide

But multiplication IS NOT before division. It'* on the same level. People that were taught this were taught wrong and their teachers need to have their certification revoked.

PEMDAS and BODMAS are the same mnemonic in theory.

Re-written to remove the division, and hence the confusion proves that 288 is the correct answer.

48 * .5(9+3)

BEDMAS is not a rule, it was just to help you out remember the order
its like I before E except after C, but theres always an exception.

482(9+3) is the same as


48
---------
2(9+3)

which is equal to 2

Look at how I rewrote the problem. It makes it make more sense and shows the correct answer is 288.

Also, for it to REALLY mean what you said it means, it would have to be written
48/(2(9+3))

Which it'* not.

You can also write it as 48/2/(9+3)=2 or 48/(2(9+3)=2

48/2(9+3)=288

Break it up and you will follow it.

48/2 * (3+9) = X
48/2 * (12) = X
24 * (12) = 288

For giggles I asked my 13 year old daughter to look at the formula and give a answer. She did it in her head, and got 288.
