answer 288.
ask your teacher( in assumption you are studing). if he/she says somthing else, he/she is completly retard:)

[div.ide]

I need someone to make "multiply" account, so we could argue who's more important

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

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.

Actually, that paranthesis does not mean anything in this calculation, just write 12 instead of (9+3) and see the fact.

Could you please solve this:
sin2pi = ?

[kingW3]

sin2pi=0
but it's mostly used when there is an variable like x or y or even pi but when it's with numbers it should be treated like 2*(9+3) but that isn't 100% right it can also be 2(9+3) as entire statement as said above

[GmX]

lol you all get confused whike using /

48÷2(9+3)

48÷2 *(9+3)

48     ÷          2         *         12

but you all use

48/2(9+3) and fuck everything up....

MAN what did they teach u in ur school ?

[div.ide]

sin2pi=0

So, pi is not a number anymore?

Hey, I wanted him to evaluate this, to see him contradicting himself.

[kingW3]

pi is a number but it's treated like a degree here,i will wait till he comments than we shall countinue with arguing muhahah

[donjacrtasamir]

i don't get u guys

can u pls solve this for me


8            ÷                          4              *                            2    =

how much is it


and about this shit with pi

Spoiler for Hiden:

sin (2*pi) = 0 in degrees in radian it's the same
if you take pi=180 degrees or pi=3.14 in radian it is the same fucking thing  sin (2*pi)=0

sin(2* pi) in degrees = sin(2*180)=sin(360)= 0   
sin(2*pi)  in radian    = sin(2*3.14)=sin(6.28)= 0

Soooooooooooooo

2(9+3) turns into 2 * (9+3) //no parenthesis

but

2pi turns into (2*pi) // inside parenthesis?

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?

I wrote
sin2pi
you calculated
sin(2pi)

Where did you get this parenthesis from? You claim there should be none, yet you put it.
And no, this is not about difference about degrees and radians. I's about doing it from left to right.

And do you know the usage of ( ) ?
BEcause when Im reading your posts I think you dont udenrstand that.

GG THERE IS JUST NO WAY TO ARGUE WITH SOME OF YOU GUYS


 the answer is 99 as xmany said

[div.ide]

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, multiplied by pi it should give you 2.85664212 [google] [wolfram] 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).

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.

[div.ide]

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.

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.

[FU I am PeNGuiN]

how could this crap could evolve in to this much discusion?

stop this math crap, i posted a myth of the week
