This is how I view it.

That is totally another lesson , don't mix lessons together .

On Topic : An eleven years old kid can answer this stuff where i live . I wonder what will you guys do with some harder operations

Precedence of operations :

The order in which the operations are performed determines the results . Assume that you have the expression

5+6*2

If the addition is done first the result of the expression is 22 , while he the multiplication is done first , the result of the expression is 17 .

The rules of precedence for evaluation of an expression is performed in the following order from the highest to lowest :

1-Operations within parentheses .
2-Exponentiations .
3-Multiplication and division operations .
4-Integer division operations .
5-Modulus operations .
6-Addition and subtraction operations .

Multiple operations at the same level ( such as multiplication and division ) are performed from left to right .

Here is a bit tricky Example :

3^2*2+4*3

i will leave it unanswered for now .

well essentially your writing the equation as 48/(2(9+3)) rather then 48/2(9+3) which is a totally different equation

in reality you should look at it like this (48/2)x(9+3)

Epic thread on this in the misc over at bb.com, is that where you got the idea?Went on for almost 90 pages and had 3000 votes.. Ended up about 50/50 between 2 and 288.

PEMDAS

Parenthesis
Exponents
Multiplication / Division
Addition / Subtraction

You work left to right on MD and AS.

48/2(9+3)
48/2(12)
24(12)
288

An engineer, math professor, etc would never write the problem down like this in the first place.

Question:
So the MD in PEMDAS is just Multiplication and Division lumped together? You don't actually do the Multiplication first, then the Division?

That seems to be there the confusion lies. I'll admit I chose 2 before I read the thread.
So my work would be:

48/2(9+3)
48/2(12)
48/24
2

That's incorrect?

48 is devided by 2 9+3s

2 is part of the parentheses. It is saying there are 2 9+3 in that equasion. Like me saying before 2X

Lol love how this simple equation fools so many ppl...yes multiplication and division go in order of which appears first, reading from left to right.

48/2(9+3)

yeh it was an insult but nether the less at school i was good at math iv let it drop since shame as i enjoyed it but nether the less, it is a simple equation. i suppose i found it easier as i prefer to write out my sums like that with brackets i find it easier to work out rather then lines and lines of working out 1 line with brackets is all i need

Truth be told this isn't so much brain power as it is habit :/
I doubt on paper you'd write the equation the same way you would on a computer. On paper you'd emphasize some parts or write them in a particular way to make clear to yourself and remember what your equation is. Naturally when you're faced with an alternative view of the same equation it causes some confusion.

2(9+3)

again by ignoring the division before the multiplication your skipping ahead of yourself, work left to right

as i said in my last post not to you but the other guy i find these equations easy as they only work in 1 direction thats -> ie 2(100/10(11-1))= 200 it works in only 1 direction no matter how big it is. im not saying 2 isnt part of the equation though but its part is contained within a division not a multiplication

You're doing the order of operations... out of order. lol MD and AS are worked from left to right.

You cannot rewrite the equation as 48 over 2(9+3). That would have been written as 48/(2(9+3)).

for it to be 288 it would need to be 48/2*(9+3)

with it being 2(9+3) it implies that (9+3) is part of the 2.

The answer is the equasion is horribly written it can go both ways.

The whole point of this is to see how many chose which answer, ask Ruyi to show us who voted for which, and make fun of whoever voted for 2 :sohappy:

2(9+3) does not imply (2(9+3))
2(9+3) implies 2 * 12 -> no brackets

48/2(9+3) implies

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

bracket and star (*) multiplication are the exact same thing

look it cant go both ways your not working left to right, this 48/2*(9+3) is right although easier to understand it if you write like this (48/2)*(9+3)

simply put

48/2(9+3) =/= 48/(2(9+3)) (<-- which is how your writing it)

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

dont matter how you want to write it just aslong as you do it in the right order, but this is becoming a joke get a calculator out and type any of these in iv put down then try yours, you will find it dont work

2(5) = 10
2*5 = 10

Same difference.

And why does 48/2 not imply that the 2 goes with the 48?? From left to right MD.

Distributive property makes sense. Though PEMDAS does state from left to right but it would need to be written 48÷[2(9+3)] for it to be 2. I do stand corrected in my belief that it was 2.
The way Amarisa is looking at it:
(48) ÷ [2 * (9+3)]
(48) ÷ [2 * (12)]
(48) ÷ [24]
48 ÷ 24 = 2

The way it needs to be looked at:

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

Amarisa you need to review your math notes from grade 7.

You're not following the simple rule of Order of Operations. What you're doing is multiplying before adding whats inside the parentheses and not reading from left to right.

Here in Alberta we were taught BEDMAS(PEDMAS):
Brackets (Parentheses)
Exponents
Division
Multiplication
Addition
Subtraction

48÷2(9+3)
48÷2(12)
24(12)
288

Like I said it has been explained many of times, but you don't seem to understand.
