edit : just try to calculate with a calculator , thx

try to calculate 2+2*2 and on most calculators you will fail...


but i still think the answer is 2 :p

Lol i wasn't even thinking, dividing has an advantage over multiplying and brackets are done so it would be 2 if it was like this
48/(2(9+3))

look    48%2 ( 9 + 3 )

simply     48 &   ( 2 . 9 ) + ( 2 . 3 )

now   48 &   18  + 6

           48 & 24 = 2 idiots :D

Divide and multiply must be done first, if they are together, we just calculate from left to right.
So
first 48/2=24
and 24*(9+3)=24*12=288

And here is an harder question:
We have 9 marbles, 8 of them is same weight, 1 is a little heavier. We can't understand with hand, but we have an equal arm scale, who can find which marble is heavier in just 2 scales?

God thats stupid... if there are double (()) then maybe its 288, but sience you must do () first then only good answer is 2 :|

ps. Maybe not double (()) cause it wont change anything :P
Before you dont POINT to do the 48/2 FIRST.. the answer will be 2.

Do any of you got math in high school,elementary school or college i don't know how the fuck you pass it with this shitty knowledge,div.ide is right if you put it this way it can mean both.Anyway the correct answer is 288 done by google calculator,also nevermore if it was double brackets 2 would be correct answer now go to elementary school again
nazarovac you can't simply put 2* in brackets it goes like this
48/2*(12)
24*(12)=288

U are wrong man.
Distributive property of multiplication over addition. Early Algebra problem.

The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire statement and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (2*9+2*3). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it. You do NOT compute this expression from left to right until you use Algebra to simplify the statement 2(9+3).

So this can be rewritten as:
48 / (2*9 + 2*3)

Which leaves us with

48 / 24 = 2

Answer = 2.
Title: Re: Math
Post by: iNevermore on July 25, 2012, 00:09

Title: Re: Math
Post by: kingW3 on July 25, 2012, 00:17
Actually this is the equation you're looking for
48/2*(9+3)
24(9+3)
(9*24+3*24)
Also in math teachers told us to check our answers in equations with x you replace the x if you get different result it means you're wrong so check this without it
48/2*(9+3)
24*12
So those 2 answers can't be correct which means there is a mistake

guys come on lets end this stupid Problem :D the answer is 2  End Of Story stop Annoying plz and for ppl who said its 288 its also True But not 100% i mean if u answered this question at some exam with 288 u will not take the question points because  as we all know  Beating is stronger than the division

so   2 (  9+ 3 )  before 48  . 2 stop spam here plz i think its clear for all of you now

Actually why do we need it since division goes first then multiplying,everyone who i asked(all of them did math in math college said that).If the equation was written like this 48/2*(9+3) 288 would be the right answer

Title: Re: Math
Post by: kingW3 on July 25, 2012, 00:43
You solve the brackets ok i'll do it
48/2*(9+3)
48/2*(12)
24*(12)=288 valla
since 2 isn't in brackets
Title: Re: Math
Post by: GmX on July 25, 2012, 00:48
Ok Brother i will explain it for you Simply plz read it 1 more time then post


48% 2 ( 9 + 3 ) =

 now we  leave 48  and solve 2 ( 9 + 3 ) and the way u must solve it is just like this
     2 ( 9   + 3  )  =   ( 18 + 6 ) Cool ?  now its just like this 48% ( 18+6)  =   48 % 24 = 2 so u got it now or what? 
Title: Re: Math
Post by: zxcv on July 25, 2012, 00:50
I can assume that there is some ppl who dont know the answer but im sure that some guys here just trolling.


As said many times u should try calculator. The pictures with calculators in link posted few posts upper is confusing. Two calculators show 2 and other 2 show 288. There is one correct answer and it is 288. Owner of calculator witch show 2 should ask his money back. Mathematics is exact science.

48/2*(9+3)  firstly brackets 48/2*12

now u can do 48/2*12 = 24*12 = 288

or even 48*12/2 = 576/2 = 288

Ok check it out you uber math pros. why arent you just simply doing the fucking thing from left to right . Yeah its right you HAVE do the stuff IN the brackets first , but who said that multiplying the 2 with the (9+3) has priority? So its just like that : 

48 / 2 * (9 + 3) =    // now you are doing the stuff in the brackets first which is 9+3=12  and you can remove the brackets now , you dont need brackets for a single number.

Then it goes like this :

48/2 * 12 =

and then go either this way  576/2 or this way 24 * 12 .

So no matter if you divide 48 with 2 first and then multiply with 12 or multiply 48 with 12 first and then divide by 2 , you will get   288

On any exam I'd write 2 cause of this:

Try to make it like this:

(I replace 48 with X , and put 2 to try if its correct)

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


Now, i replace 48 with X again , but this time i put right side 288 ( = 288 ) i get :

x / 2(9+3) = 288
x / 2(12) = 288
x / 24 = 288
x = 288*24
x = 6912 > Not correct (not 48)

So, answer is 2. My opinion.

Post by: div.ide on July 25, 2012, 01:34
Fuck, I had nice wall of text incoming, and erased all by accident. RAGE.


I'll shorten it.

This equation uses informal implied multiplication, which does NOT have strict, formalised rules to follow, and is used here improperly, without proper brackets to clear out ambiguity. Therefore, in my eyes, is nonsense, and both versions are kinda correct. It's like, Schrodinger's math :D
Though meme author was brilliant troll.

So, example. Left to right logic.

Sin (2*pi) = 0 - that's for sure.

But this:

sin 2 pi = sin(2) * pi = definitely not 0

Because who said you are supposed to multiply first? Oh wait, everyone does that. Looks like everyone disobey most basic rules.

See what I did there? I know sine example is somewhat dumb because it's traditional, but there are no formal rules either. Again, use brackets or... (yes it's a link) (http://youtube.com/watch?v=Xw-m4jEY-Ns&feature=player_detailpage#t=70s)
Otherwise it makes no sense.

x/2(9+3) = 288
x/2 * 12 = 288

correct
btw most of you posted it like this 48/2*(9+3) which would make 288 the answer

IT IS #$%& TWOO.

ANOTHER WAY TO SOLVE IT:

48/2(9+3)
48/ (2*9+2*3)
48/ (18+6)
48/24
2

Post by: Johnny. on July 25, 2012, 02:03
nahhh its 288 for sure .

just treat it all like a fraction

so this 48÷2(9+3) is like this   48/2   *    (9+3)  and result is 288.

but in case that the problem would be like this   48÷ [ 2 (9+3) ] the fraction would look like this :

48   /   2(9+3)   (so in this case 2(9+3) is under  48 in the fraction )  and the answer would be 2.

but since its not , the result is 288.

Post by: Facemelt0r on July 25, 2012, 02:04
You are wrong, Stalker.
Since when 2*(9+3) = 2*(12)?

2*(9+3) = 2*9 + 2*3 = 18 + 6 =24

so,

48 / 24 = 2

end of discussion.

Hmmm... :D

red should be done first.
=48/2*12
and then, just go from left to right.
=24*12
=288
You CANT start from right to left, u must calculate from left to right. IF it was

48/(2[9+3]) it will be 2, because of paranthesis. But there is NOT.

Quote
The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire statement and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (2*9+2*3). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it. You do NOT compute this expression from left to right until you use Algebra to simplify the statement 2(9+3).

So this can be rewritten as:
48 / (2*9 + 2*3).

Which leaves us with.

48 / 24 = 2.

Answer = 2.

Lastly for those using Google or any other online calculator. These do not understand many theorems or properties so you must explicitly explain what you mean. There is a difference between 48 / 2 * (9+3) and 48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second reads 48 / (2*9+2*3). Be very careful with your signs.

I was too lazy to write it myself so yeah i copy pasted..

simply first ( ) ->  48/2*12  =

then all operations have same priority so we go from left to the right

  = 24*12 = 288

this is problem because not all math pros arent agreed if 2(2+2) has priority over 2*(2+2)
but most of them say simply 2(2+2)=2*(2+2) so they say it has no priority

And why that?

Rule is simple , first brackets BUT ONLY whats is inside of them . Then goes division , no matter what , and then you multiply. You think just because 2 stands along the brackets it should go that way. Anyone who has done proper math will say that division goes first no matter what , and rule for brackets , as i said is onyl for what is the brackets.

Still it is the rule in math. And it is logic that you do left to right , like the way you read ( there are exceptions in arabic )

I see that king wrote same thing

Lol i wasn't even thinking, dividing has an advantage over multiplying and brackets are done so it would be 2 if it was like this
48/(2(9+3))

YES this is the part they couldn't understand, 2(12)=2*12 is multiplication, so it must be done before the 48/.

Take first elemntary book and you see that in this math you have to do () first... sicne 2 stands before () means you must multiply every single sign inside the  () with 2 ..
and this is true, it works from left to right. and we already do the operation in () first, then, remaining operations are multiply and divide, they are same priority so go from left to right.

So lets think of the number 24; 24 = 18+6 right?

Now lets write "18+6" in parenthesis of 2 which leads us to 2(9+3)

Now if you have completed elementary school you should be able to understand that 2(9+3) is an entire statement and it CANNOT be broken up.

So lets get back to 48/2(9+3)

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

Now lets write "18+6" in parenthesis of 2 which leads us to 2(9+3)

Now if you have completed elementary school you should be able to understand that 2(9+3) is an entire statement and it CANNOT be broken up.

So lets get back to 48/2(9+3)

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

I hope everyone can uderstand now. In this case Left to right thing doesnt work.
that's not an explanation.
number 24 can be wrote down as a 48/2 which is also part of equatiation.


Also 48/2 can be written down as a 48x0.5

so there should be no talking about priorites in dividing and  multiplying.

Do you even understand? 2(9+3) is an entire statement which CANNOT BE BROKEN UP

Edit: Oh and also lets try your way, lets write 24 as 48/2

= 48/48/2
= 48.2/48
= 2
I hope this was simple enough for you.

On exam you would get above example and the answer would be 288 but in this case answer can also be 2
It can be broke but as i said above writing 2(9+3) can also be considered as [2*(9+3)] in which case the result would be 2
btw tyger 48/2(9+3) can't be wrote like this 48/(9*2+3*2) it can be written like (9*24+3*24)

So lets get back to 48/2(9+3)

2(9+3) = 24

Why don't u first divide the 48 to 2 then multiply with that (9+3)=12? the paranthesis musn't make u give pesmission in the operations which is OUTSIDE the paranthesis, so 48/2(9+3)=48/2*12, this is the part you are wrong, its NOT 48/(2*12) so you CANT do that multiplication first, you must divide, then multiplicate. Lets make this even easier looking  for you.

courier power ure right,even u writed as a fraction  look here:

we have this fraction ok?48/2 and its multiplyed by 12  (9+3)
we reduce terms 12 with 2 and it remains 48*6=288

so i was wrong.also 12 can be written as 24/2
and if u make 48/2*24/2 will be same as 24*12 wich is 288.
so here is the demostration.

Tell me where's sense of it, when you claim implied multiplication has no special precedence, then violate this rule in your very next sentence?

GG? Why don't you just explain why do you use the same, implied multiuplication in two borderline different ways?

In case you still didn't get sie sine thingy - it's quite obvious that we do stuff from left to right, agreed?

So, you claim we undoubtly interpret xy as x * y

Let's do it for sine thingy, we'll get
sin2*pi

Now we do it from left to right. Sine of 2 (radians) is approximately 0.909297427 (https://www.google.pl/search?q=sin+2), multiplied by pi it should give you 2.85664212 [google] (https://www.google.pl/#hl=pl&output=search&sclient=psy-ab&q=sin+2+*+pi) [wolfram] (http://www.wolframalpha.com/input/?i=sin2*pi&dataset=) which is... not quite 0. (clicky clicky numbers will link you to Google The Holy Grail of Maths and Wolfram The Oracle of Maths, in case you wanted to check how I calculated these numbers).

Now convince me that without doubt 2(9+3) turns into 2 * (9+3) and not (2 * (9+3)). There is doubt. It's not defined clearly enough. It leaves interpretation up to you, allowing both answers to be correct UNLESS everyone agrees to create a set in stone rule, which will not likely happen.

So, clarify your maths with proper usage of brackets, or... (yes, it's a link). (http://youtube.com/watch?v=Xw-m4jEY-Ns&feature=player_detailpage#t=70s)

You just cant compare sin(2pi)  with 2(9+3) . Fractions and multiplikations of pi  are always treated as a whole. And if you apply sine to them you MUST write it in brackets like sin(2pi) or sin(pi/4).

Beside that , sine is a FUNCTION , not an operation like multiplikation or substraction. You cant write a function  f(x+2)=y   like  f(x) + f(2) = y, cause functions apply to the stuff in the brackets as a whole.

Dont talk about things you dont have a clue about , better go bust some myths.
Title: Re: Math
Post by: div.ide on July 26, 2012, 19:23
Pi is a number as well as (9+3). What gives pi special status? Why there's a difference between 2(pi) and 2(9+3) or 2(12), other than value in brackets? You claim there is a rule for that, while there's none. Precedence of implied multiplication varies by source, there's no consensus in that matter. You can't simply  use it as it was fundamental.

Quote
You cant write a function  f(x+2)=y   like  f(x) + f(2) = y, cause functions apply to the stuff in the brackets as a whole.
Where did you find this? Because it was nowhere in my post. Don't make up statements out of nowhere.

Functions apply to what's in bracket, correct. But where's bracket? Right, traditionally we assume it's here -> (2pi), because otherwise you could just write down sin2 * pi and everything would be clear and done lef to to right. (It's still assumption, though, because brackets are not written.)

Then by what rule same logic is not appliable here? You could simply write down multiplication explicitly, and no one would argue with it then. But now, it's either just an error, a misspelling which in first place makes it stupid to even consider the problem, or it's put like this intentionally, which supposedly means something. I ask you - what makes you belive it's supposed to be understood that way and not the other one? Any written rule you can quote? Or just  your opinion? Because latter one is in no way arbitrary here.

I can give you another example with indentical issue:

6/2x

If you make x=3, how much will it be?

For me, it's like writing "i help uncle jack off the horse" without punctiation or capital letters. You're guessing the meaning, and can't be sure what did author really mean, because of those little details.

simply first ( ) ->  48/2*12  =

then all operations have same priority so we go from left to the right

  = 24*12 = 288

this is problem because not all math pros arent agreed if 2(2+2) has priority over 2*(2+2)
but most of them say simply 2(2+2)=2*(2+2) so they say it has no priority

If it was this 48:2(9+3) it would be 288 but since it is 48÷2(9+3) the answer is 2

BTW 48÷ (a guy with a dick in his hands), 2(9+3) (a guy with a lazy eye and only 1 ear) so the answer is 2 gay guys and again the answer contains 2 so the answer is 2 def!

First we calculate the (). so 48:2*(9+3)=48:2*12
Since * and : have the same priotiry we do the calculation placed at the left so : = 24*12=288

This is wrong, this is just something accepted to be like. But many mathematicians disagree.
