48÷2(9+3) = ????
As seen on Rennlist and some other forums around the globe:
48÷2(9+3) = ???? Please answer poll before adding comments. -Z-man. |
I remember that the first rule was always do the operation inside the parenthesis first. IIRC, the next would be multiplying the # inside the parenthesis by two before doing the division. Sort of like 48/2x (with x=9+3) so I vote for a final answer of 2.
That is my final answer. |
Whatever you do, don't divide by zero or the universe will implode.
|
I'm sticking to 2 after consulting my high school junior. SmileWavy
|
If you work the problem from left to right using basic algebra the answer is 288, if you over think it the answer is 2.
|
This reminds me of the SNL skit "Common Knowledge"
|
I get 2
|
PEMDAS.
This is third grade math, idiots. |
I still remember (P)lease(E)xcuse(M)y(D)ear(A)unt(S)ally from Mr Neuburger's 9th grade algebra class.
Parenthese Exponents Multiply Divide Add Subtract... so answer should be 2. |
How is this even a serious question? The answer is 2.

Hierachy.
288. |

Order of Operations - PEMDAS
Note: in the UK they say BODMAS (Brackets,Orders,Divide,Multiply,Add,Subtract), and in Canada they say BEDMAS (Brackets,Exponents,Divide,Multiply,Add,Subtract). It all means the same thing! It doesn't really matter how you remember it, just so long as you get it right. Multiplication does not take precedence over division. |
48÷2(9+3)=
48÷2(12)= 24(12)= 24*12= 288 |

The division symbol is confusing..
why not write the problem in a manner that is more easily understood.. http://forums.pelicanparts.com/uploa...1302487483.jpg |
I'm thinking... everything on the left of the division sign = numerator. To the right = denominator:
48÷2(9+3) 48/2(9+3) 48/2(12) 48/24 2 |
How can it NOT be 2???
Have they changed math in the twenty five years or so since I'd learned this? |

Parenthese Exponents Multiply/Divide Add/Subtract You don't multiply before you divide, you do them at the same time, left to right. You don't add before you subtract, you do them at the same time, left to right. Here it is from a grade school math web page: Order of Operations Quote:

+1. (Rules are rules!)
It all depends on where you connect the 2: is it connected to the 48, or the (9+3). So -- is it: (48 ÷ 2) * (9+3) or 48 ÷ (2*(9+3)) ?? Order of operations comes into play here. Also -- if one rewrites the expression, substituting " ÷ 2 " with "* 0.5" the answer seems clear to me: 48 * 0.5 * (9+3) -Z-man. IMHO, the answer is 288. |
This demonstrates why the ÷ is never used in actual mathematics.

funny on how split the answers are, and how strongly people feel about theirs. lol..
that being said, its 288.... |
I also say 288 - b/c the order of operators is the same for any associative operators; therefore, work left to right
|
I forgot about the left to right rule. 288
(I wonder if it would be 2 in Israel since Hebrew is written right to left?) |
Answer is 2
|
2.
The stuff on the left, divided by the stuff on the right. |
48÷2(9+3) = ????
I gots 48 eggs. I'm gonna divide 'em by a number. What number, you ask? Why that number is 2(9 + 3). Anybody disagree that 2(9 + 3)=24? If yes, return to 8th grade Beginning Algebra. Anybody disagree that 48 divided by 24 is 2? If yes, return to 3rd grade. Sheesh. :rolleyes: |
Well, I voted for 288 early on and without looking then felt like an idiot when I read the early results.
I'm a poli sci major so I'm used to being bad at math but I'm also a contractor who has solved many real world math problems. Now I'm just curious. Jesse |
This reminds me of the argument I had with son's 3rd grade teacher a long while back. She argued that 1+2x3 = 9 instead of 7. In fact, I had an entire roomful of elementary-school teachers argue that it was 9. This partially explains why students have so much trouble with basic algegra and why science and engineering education in this country has gone to $*&@!....

Order of operations.
Multiplication and division are evaluated left-to-right. Hence, 288. |
Brackets first, then left to right
288 |

48÷2(9+3) Start Step one, Perenthesis, gives us: 48÷2(12) Next step, Exponents. None of those, so we move on to Multiplication and Division, going left to right. 48÷2 = 24, leaving us 24(12) 24*12 = 288 We will ignore AS because we are done. And if you don't believe me: http://tinyurl.com/3qw3ko6 |
only a commie would say the answer is 2
|
The only way the answer is 2 is if you drove to it in a well sorted 944.

Don't miss out on the deal I'm offering in post #36!!! |
I think the real question is why is an admin posting a question that's considered trolling.
48÷2(9+3) = ? | Know Your Meme BTW I got 288 |
