I tripled checked

and I stand corrected.

It's a visual trick.

Order of operation says inside ( ) not outside.

then you have to go left to right and not resolve what's outside the parentheses

because everything is the same order of priority.

We have a tendency to set priority because the 2() seems grouped when it's not.

the it doe read.

48÷2 x (9+3)

48÷2 x 12

It's right to left after what is inside the parentheses are solve. :lol::hmm:

the multiplication is not grouped but separe of the ()

This 2() is 2x() not (2())

so it's 288

The answer is 2. BC...... The parenthesis implies that you must add those two numbers together first. The 2 before parenthesis implies multiplication. So it's 2 x 12. Which equals 24.

48 divided by 24 = 2.

48 divided by 24 = 2.

You divide before you multiply because division comes first . You always work left to right

Bullshit you have to multiply before division. You telling me I have to distribute the 16 to 9+3? Lies!

Yeah I was talking mad shit in the first few pages, but now I do get that the answer is 288...

So I OCKed myself too... :lol:
Lol it's all good. As long as you understand why. That's what we care about.

But lol @ people maintaining it's 2.

I will keep posting this til someone reads it

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first. If you're not sure of this, test it in your calculator, which has been programmed with the Order of Operations hierarchy. For instance, typesetting this into a graphing calculator, you will get:


calculator screen-shot: 15 / 3 * 4 = 20

Using the above hierarchy, we see that, in the "4 + 2×3" question at the beginning of this article, Choice 2 was the correct answer, because we have to do the multiplication before the addition.

(Note: Speakers of British English often instead use "BODMAS", which stands for "Brackets, Orders, Division and Multiplication, and Addition and Subtraction". Since "brackets" are the same as parentheses and "orders" are the same as exponents, the two acronyms mean the same thing.)
http://www.purplemath.com/modules/orderops.htm

Mnemonics are often used to help students remember the rules, but the rules taught by the use of acronyms can be misleading. In Canada the acronym BEDMAS is common. It stands for Brackets, Exponents, Division, Multiplication, Addition, Subtraction. In other English speaking countries, Brackets may be called Parentheses, or symbols of inclusion and Exponentiation may be called either Indices, Powers or Orders, and since multiplication and division are of equal precedence, M and D are often interchanged, leading to such acronyms as BIMDAS, BODMAS, BOMDAS, BERDMAS, PERDMAS, PEMDAS, 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.

10 - 3 + 2 ,
The correct answer is 9, which is best understood by thinking of the problem as the sum of positive ten, negative three, and positive two.

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



Position within the expression is used to determine the order of evaluation when two or more operators share the same operator precedence. Consider the following:

A = 6 / 2 * 3

In this case, A equals 9, since the division operator is to the left of the multiplication operator. The subexpression 6 / 2 is evaluated before the multiplication is done, even though the multiplication and division operators have the same precedence. Again, parentheses can be used to override the default evaluation order:

A = 6 / (2 * 3)

In this case, A equals 1, because the expression inside parentheses is evaluated first.

A useful rule of thumb is, "when in doubt, parenthesize". Some examples of expressions are provided in the following table.

I can't believe this thread has gone 12+ pages.

Let's get a quick check: how many of the posters have completed Cal I (Differentials)?
 
Lol it's all good. As long as you understand why. That's what we care about.

But lol @ people maintaining it's 2.

this shit gonna be the new Kobe vs. Jordan...the new Android vs Apple......shit is serious ...cats breaking out the white boards and calculators in this thread... talking about their advanced math degrees and shit
 
Google this problem and put "wtf" at the end in the search bar. This problem is a thread on every forum in the universe in 1 day. :eek: :lol:
 
48/2 = 24*12 = 288.

Where did you get the (=) sign in this 48/2*12 ???

You completely redistributed the problem into an equation without any math.

I did what was in parentheses first (9+3) = 12

After you do that you work the problem from left to right since division and multiplication carry the same weight.

48 divided by 2 EQUALS (=) 24, times 12 (since the parentheses were solved it is now multiplication) which equals 288.
 
Wow, can't believe this shit was posted today and generated so many views. Good shit to the OP.

With that said, the correct answer is 2.

If you got 288 you're making it harder than it is(or probably don't know what you're doing in the first place).
:cool:

Shit get real when math is involved.

Just when we finally moved past Jordan vs. Kobe and started to move past Android vs. Apple :hithead:
