2 or 288? Terrible notation, but what do you think should be right?
-
Date: Mon, Apr 11 2011 17:18:09
2?
-
Date: Mon, Apr 11 2011 17:29:06
order of operations says it's 288. please defend answers
-
Date: Mon, Apr 11 2011 17:37:39
Nevermind..i'd say its 288 as well now, thought stuffs in brackets were done first >.>
-
Date: Mon, Apr 11 2011 17:52:26
use PEMDAS. that way u kno what order ur going in. Parenthesis, Exponents, Multiply, DIvide, Add, Subtract. in that order. therefore the answer would be 2.
-
Date: Mon, Apr 11 2011 18:11:00
remember multiply and divide are on equal terms (as well as addition and subtraction) order of operations also says to work left to right

lol oops i guess ur right, :P

Date: Mon, Apr 11 2011 19:45:53
first you do parenthesis 48÷2(12) division or multiplication from left to right, in this case division, the parenthesis are just throwing you guys off. 48÷2(12) is the same as: 48 ÷ 2 x 12 therefore, 24 x 12 = 288 not sure why all the confusion

the answer is 288 as wonder said earlier. Something interesting my white friend told me; If you put 48÷2(9+3) in a calculator you get 2 and if you put 48/2(9+3) you get 288.

It's 288. It's as if this: (48÷2)*(9+3) type this on google: 48/2(9+3)

lol i was wondering the same thing probably what the dealio is is that it might have been like you cant express a fraction correctly when typing. for example if you want 48 all over 2(9+3) then yes that would be 2. if you write it the way you wrote it right now, then it would be 288, it all depends on how it is expressed, so it may have caused confusion. In the case of computers, extra parentheses are required -

its a loop hole in the canadian law if you dont have a "skill challenge", the contest is classified as gambling, so you need special license for that. if you have a "skill challenge", it is considered a competition and not gambling. basically its not ok to have a contest which is pure luck. you need to earn your money. -

yo y are there so many ppl voting 2 okay 48/2(9+3) means 48/2 x 12 which becomes 24 x 12 = 288 if the equation was 48/[2(9+3)] it becomes 48/[2(12)], or 48/24, which is 2 unless theres that bracket u dont do the multiplication first hur durrrr

48/2 (9+3) ---> brackets first 48/2 (12) or 48/2 x 12 ----> Division comes first in order of appearance hence the reason we divide first 24 x 12 = 288 /thread

it's 288. multiplication and division go together. whichever comes first is whatver to do first.

Multiplication and division are the same operation guys. Parenthesis, then left to right.

google it and its 288 (48÷2)(9+3)
-
Date: Tue, Apr 12 2011 01:59:15
oops i meant to write 288 not 2. you do the parantheses so you get 48/2(12) so then it's 48/2 which is 24 then times 12 which is 288.

Yup. Parenthesis go first, then division and multiplication are the same operation, so they operations go left to right. The answer is 288. -

I don't know if it is just me but I find it highly weird and unusual when you guys use "parenthesis" instead of brackets.
-
Date: Tue, Apr 12 2011 06:01:17
that's because parentheses are () while brackets are [] but they serve the same purpose. i think some people learn bodmas? B-Brackets first O-Orders (ie Powers and Square Roots, etc.) DM-Division and Multiplication (left-to-right) AS-Addition and Subtraction (left-to-right) so you might've learned the term brackets instead.

-
Date: Tue, Apr 12 2011 19:35:17
Difference between a parenthesis and a bracket is that there are brackets to indicate that you do that side first Like I said before, 48/[2(9+3)] Will mean first, do 9+3=12 then 2 x 12 = 24 then 48/24=2 But this equation doesn't have brackets, which means you just go left->right after the parenthesis

Ok! Taking 48÷2(9+3) to be equivalent to 48/2(9+3), the ambiguity comes from writing a fraction in a single line. Implied multiplication by proximity and explicit multiplication (using the multiplication sign) give the same result, but the former is considered a single term. Ex.: ab = a×b, but ab is deemed a single term. If you were to write 1/ab, people would assume it meant 1/(ab) and not (1/a)b [= b/a] So, in 48÷2(9+3), it's taken to mean 48/[2(9+3)] and not (48/2)×(9+3). If the original expression was written as 48÷2[B][COLOR="red"]×[/COLOR][/B](9+3) I would say the result is 288, but to be absolutely sure, it should be written as (48÷2)(9+3). If 48÷2(9+3) = 288, then (8a^2)÷4a = (8a^2)÷4(a) = (8a^2)÷4×a = 2a^3. -

yeah, but in this case it is written on a single line and picking the unseen option is cooler ;D

You haven't given any evidence to suggest that Asians are smarter. Consider searching for a peer-reviewed study. On a personal note, all the smart people I've ever known have been either Indian or white. From my experience, Asians do get good grades in general, but they lack the critical thinking that the truly smart people have. -
Date: Wed, Apr 13 2011 03:38:55
imo it should be 2. maybe im just dumb but: my TEACHER said we need to eliminate first the parentheseseses sooooo: 48/2(9+3) ---> 48/2(12) but 12 still hass a parenthesis to eliminate that, we need to multiply the 12 to 2 48/2(12) ----> 48/24 48/24 = 2! well thats just me....

I see this a lot. Many Asians study/learn material solely for quizzes/tests/grades, while not understanding the principles/logic behind things. I feel that I have solid critical thinking myself and that there ARE quite a few great Asian thinkers, but your point is definitely valid. -

hi everyone This question has appeared in many forums these few days, I don't really know who started this, but I see this question as a mean to troll, to create ''chaos'' in the forum. Well, I'd say the answer is 2. Personally I've debated in one of those forums and really there is not really an absolute answer to this because different people think differently. So I'm here to ask all of you a question. 1÷2x gives you? and 1/2x gives you? I shall break it down further. 1/2x is an ambiguous expression as it denotes two different meaning to people. It can mean 1/(2x), you can also see it as (1/2)x. For me I normally see it as 1/(2x). In words, we say, ''half of x''. Do note that / and ÷ denotes different meaning and / is used for fractions basically. So if you were to meant 48/2(9+3), I'm sure the ambiguility would be much greater.
-
Date: Wed, Apr 13 2011 13:09:07
I think the answer is 2 because let's say 48÷2(9+3) is 48 ÷2(a+b) therefore it is 48÷2a+2b and if the a is 9 and b is 3, the answer would be 2 and ÷ is the same as / so 48/2(9+3) which is 48 2(9+3) and 48/24 is still two

nope, to simplify things I'll let (a+b) =c 48÷2*c =24*c =24*(a+b) when a = 9, b =3 =24*(9+3) =24*12 =288 -
Date: Wed, Apr 13 2011 14:15:26
Its 288. Just add 9 and 3 = 12. Then divide 48 and 2 = 24. Then multiply 24 and 12 therefore the answer is 288. :)
-
Date: Wed, Apr 13 2011 14:45:08
have you ever heard of BED MASS? 2 is the answer ...................................... EDIT : sorry, the confusion is only because of the way you type it. it can be both 288 or 2
-
Date: Thu, Apr 14 2011 01:50:34
The answer should be 288, but I could see how some people could see an ambiguity with the two different division symbols. That's why nobody ever uses them. (Except for calculators, fuck calculators.)

hahaha you think grades are related with intelligence. I mean sure intelligence helps, but lots of intelligent people realize its bullshit to take it so seriously.
