Isn't it 2?
48/2(9+3) = 48/(18+6) = 48/24 = 2


No, it goes

48/2(12)=24(12)=288

EDIT: Shit, he's right. **** you, Aunt Sally.

EDIT2: No, wait...I'm right. I retract that, Aunt Sally. Please forgive me.

I'm saying 2 because it doesn't make sense the way you did it in my head. The way I see it, 48 is being divided by the expression 2(9+3).

Division an multiplication share priority and you go left to right. The brackets trump that anyways >_>.

48/2*12=24*12=248

EDIT: =288... it's late...

BIDMAS
Brackets, Indicies, Division, Multiplication, Addition, Subtraction?

9+3 = 12 so 48/2*12
48/2 = 24 so 24*12
24*12 = 288
#16
^ d'oh, thank you. That's where the confusion is coming from, PEDMAS is completely irrelevant

EDIT: to deniflade

It's been said before, multiplication and division share the same level, and you go left to right.

Go left to right? I've never heard that rule. If this were written on paper, we'd clearly be able to see the difference, as shown by denfilade's picture.

Add the parenthesis and divide the two outside numbers.

Multiply the results together.

9+3 = 12 so 48/2*12
48/2 = 24 so 24*12
24*12 = 288

Where BIDMAS or BOMDAS is concerned, the order that division, and multiplication come in can differ as can the order addition and subtraction comes in, hence how I was taught BOMDAS in school and you where taught BIDMAS.

Again, the way I see it, 48 is being divided by the expression 2(9+3) which should be treated as a single number. If it was (48/2)(9+3) it would be 288.

Quote by wikipedia Order of Operations
M and D are often interchanged, leading to such acronyms as BEDMAS, BIDMAS, BIMDAS, BODMAS, BOMDAS, BERDMAS, PERDMAS, and BPODMAS.
These mnemonics may be misleading, especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order "addition first, subtraction afterward" would also give the wrong answer.

Haha I just finished my Year 12 half yearlies. I studied my ass off for maths the day before the exam, since I usually never study, and I've been averaging a 20% mark on all my other maths assessments. I got the results back yesterday, I got 78% and am in the top 5 advanced mathematics students

Just needed to brag about that, it's such an achievement for me haha.

actually deniflade I just realised you were wrong.

if the equation were meant to mean that the parenthesis were underneath the fraction, it would have to be 48/(2(9+3)) but since it's 48/2(9+3) it's as if it were written 48:2*(9+3), or 48:2*12 or 24*12 or 288.

Yeah, but you're treating it was (48/2)(9+3)=(24)(12)=24*12. You're imagining brackets too, mister!

Depends on how you write it.



On the left side you are assuming brackets around 2(9+3)

Well yeah, with BODMAS (or whatever name it is), the division would be done first, pretty much the same thing that brackets do, to the best of my knowledge.

no, the brackets don't change anything, because if you have an equation like this:

X / Y * Z, you ALWAYS go from left to right if you don't have any parenthesis.

And just to prove it to you, I'm going to write a program and show it to you.

Oh please don't, I don't actually care that much. This was just a distraction 'til my mum left for work and I could watch a movie.

I see it now, I guess.

I bet something like this will come up in my ****ing maths exam now
