exactly cloud

and Big V. I assume that because, like the others who think 288 is the correct answer, based on the common assumption of bedmas, which HLJ points out, excel gives the answer of 288. Doesn't the financial/ business world trust excel to give the common( generally assumed answer) If the spreadsheet is going to go off half cocked and assume a notation other than what is written, I say, Cock too.

To get the answer of 2, a person would have to rewrite the notation using brackets. [ ]

Again, it's a screwy example.

Damn, it's like some knights of some round table all up in heah.

So, tell me, (no matter what you call the damn things) how does making them curvy or making them squared have anything to do with the conundrum of the problem?

It's like...oh you know what? That 9 has a curvy bottom, therefore it must be multiplied by the half-life of the foundation of the numerator. Now, if it were STRAIGHT, that there would be a whole different story. That right there would tell you that the product of the synapse near the juncture would be 23. [\thinktanktrifecta]

I agree with UT. Order of operation.

exponents and roots
multiplication and division
addition and subtraction

so 48÷2(9+3) = ?should be written as

48/2(12) = (12x48)/2 = 576/2 = 288 (my keyboard doesn't seem to have a division sign)

You got a horse in this race, bullitt? Do you have an answer to either the math question or the semantics argument? 'Cause, I haven't seen ANYONE proven right or wrong. Just a bunch of wind a'blowin' if you ask me.

I'll ask you all again: NO MATTER WHAT YOU CALL THEM DOES IT MAKE A DIFFERENCE IN A MATHEMATICAL EQUATION IF (THOSE THINGS] ARE CURVY OR SQUARED?

Other than an answer for that, just try to look bright and say 2 or 288.

To be more precise, and to appease the dullards in the audience, how is this

different mathematically than this

48÷2[9+3] =

Even better, how does WHAT YOU CALL THEM change the mathematical equation?

This same type of discussion is happening all over the net.

My initial response was 2, and still is. I just need to solve 2(9+3) first. But I am more a right-brainer type gal, so there.

In an arithmetic context, () and [] are usually equivalent. Having different ones is handy if you have more than one set nested, to clarify which matches which. I believe it's fair to say that {} are many times equivalent and just serve as a third "layer" of grouping when needed.

However, there are many contexts in math when there's a difference, or at least a specific role. For example, ranges of numbers: [0,6] indicates a range including the endpoints, 0 and 6, while (0,6) indicates that the endpoints are not actually part of the range. When you get into matrices and other crap like that, there are definitely ways to change the meaning by changing the typography. Context and definition of terms are critical.

Well I don't believe that I'm wrong, so that can't be me that you're talking about, but since I have no more proof/evidence that I'm right I have nothing more to say about that. I did however have something to say about learned helplessness. Not my fault some are to dumb to get it without it being spelled out and turning into a bitchfest.

Sky, dear, I would contest that trolling is nurture rather than nature. And also since you are the one whaling into an argument in which you are not directly involved and you are the one calling names, that would rather put you under the bridge rather than me, no? I know how desperately you want to play Rhet in this scenario -and I see Bullitt is vying for the part too, but we already have a call out to someone's agent and are expecting them to turn up any minute.

PEMDAS
Quote:

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:
  • 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.)

Happy Monkey 04-15-2011 05:16 PM

Of course, on page 2 of that article, it says the jury is still out on whether the shorthand of skipping a multiplication symbol changes its place in the order of operations.

Aliantha 04-15-2011 06:56 PM

Quote:

48÷2(9+3) = ? is a math problem that, depending on the order of operations used, leads to two different answers: 2 and 288. It can be a hot topic for debate, and is sometimes used to troll other users because of the argument that can result afterward.
Quote:

Standard Order of Operations
If one strictly uses the standard order of operations to solve mathematical expressions, the answer to the problem would be 288, which is also the same solution provided by WolframAlpha and Google.
By convention, the order of precedence in a mathematical expression is as follows:
Terms inside of Brackets or Parentheses.
Exponents and Roots.
Multiplication and Division.
Addition and Subtraction.
If there are two or more operations with equal precedence (such as 10÷2÷5 or 7÷2*9), those operations should be done from left to right.
Therefore, the problem “48÷2(9+3) =” would be solved like this:
48 ÷ 2 * (9+3)=
48 ÷ 2 * (12)=
48 ÷ 2 * 12=
24 * 12=
288
Quote:

However, the answer 2 could be justified by the principle of implied multiplication. For example, consider the problem "2/5x."
If one strictly follows the standard order of operations, the correct interpretation would be “(2/5)*(x).”
But many calculators and textbooks state that a higher value of precedence should be placed on implied multiplication than on explicit multiplication:
Because “5x” is implied to be "5*x," it gets higher priority than "2/5." In this case, "2/5x" would be interpreted as "(2)/(5*x)."
Returning to the original problem, if one utilizes the principles of implied multiplication, then “2(9+3)” gets higher precedence than the explicit “48/2,” and would be solved like this:
48 ÷ 2(9+3)=
48 ÷ 2(12)=
48 ÷ 24=
2
However, there is a lack of consensus on the value of implied multiplication.

Now, see, I would hold that Mathematics can't allow for anything "implied". It's either multiplication, or it isn't.

I agree with this, and also think the answer is 288. But there's at least some debate even among mathematicians about the legitimacy of implied multiplication.
