According to this.

Do the brackets first so 9 + 3 = 12.

Then multiplication with the number next to the brackets. So 2 * 12 = 24

Then division 48/24 = 2.

So 2 is the correct answer. I voted for 288 (did left to right). :P

I am interested to see what FOH thinks after seeing heated discussions on this on other forums.

288: as stated above by others, parentheses, then multiplication/division from left to right, then addition and subtraction from left to right (not necessary in this case). Confirmed by excel, google, and my brain.

start with 48/2(9+3)

then 48/2(12)

then 24(12)

then 288

how did you get 2 from using this method which is the correct method im almost certain?

But your method is WRONG. The terms inside brackets must be solved in priority. Ask a math teacher.

I can't believe people are using Google as a reference for this…

PEMDAS

48÷2(9+3)

48÷2 x 12

48÷24

2

Your PEMDAS is incomplete. the MD and AS have qualifiers for left to right because they are at the same rank.

P

Parentheses first

E

Exponents (ie Powers and Square Roots, etc.)

MD

Multiplication and Division (left-to-right)

AS

Addition and Subtraction (left-to-right)

Divide and Multiply rank equally (and go left to right).

Add and Subtract rank equally (and go left to right)

http://en.wikipedia.org/wiki/Order_of_operations:

The standard order of operations, or precedence, is expressed in the following chart.

terms inside brackets

exponents and roots

multiplication and division

addition and subtraction

and:

For example, in mathematics and most computer languages multiplication is done first; in the expression 2 + 3 × 4, the algebraic answer is 14. Parentheses, which have their own rules, may be used to avoid confusion, thus the above expression may also be rendered 2 + (3 × 4).

Same reply I posted for someone else.

M and D are at the same level and therefore you go left to right. Same for AS.

d

its more like

P E (MD-left to right) (AS-left to right)

P

Parentheses first

E

Exponents (ie Powers and Square Roots, etc.)

MD

Multiplication and Division (left-to-right)

AS

Addition and Subtraction (left-to-right)

Divide and Multiply rank equally (and go left to right).

Add and Subtract rank equally (and go left to right)

it takes three licks to get to the center of a tootsie pop.....

Did you lick from left to right?

I was going to ask if you licked between the parentheses but all of a sudden that conjured up an entirely different image.

Let's keep it left to right.
