okay apparently a simple question (grade 5 i guess?). but it has people all over internet divided over it. So what do you think is right answer?

1 .
PEMDAS
Parenthases Exponents Multiplication/Division from left to right Addition/Subtraction from left to right
6/2(3)
3(3)
9
It's 9.
6 divided by 2 is 3.
Brackets so you add the 1 & the 2 and you get 3
And because of the brackets you times both 3s together.
Aye, I got 1 as well.
Parentheses first: (1+2) =3
No Exponents
Then Multiplication: 2(3) = 6
Lastly Division: 6/6 = 1
No Addition or Subtraction outside of Parentheses.
P.E.M.D.A.S.
There's no "I think", like you said, it's grade 5 math or maybe even lower.
Order of operation from left to right.
1.Parenthesis
2.Exponents
3.Multiplication
4.Division
5.Addition
6.Subtraction.
3 can be switched with 4 and 5 can be switched with 6.
In case you're still wondering, the answer is 9.
Punktrechnung for Strichrechnung.
But you can add first what's between the () which is 3.
then 6/2 which is also three.
No sign before the ( means it's x
so it's 3 x 3 = 9
YEAAAAAAAAAAAAAAAAAAAAAAAAAH I CAN DO THE MATH!!!!

I never learned to do PEMDAS from left to right.

That's almost all I can do when it's about math ;_;
And I'm totally proud of myself now that I got the right answer…
SOMEONE gimme more math exercises! I need to feel secure before my entrance exam on Wednesday...

I can work well enough with Statistics as well but I easily forget stuff and end up writing bullshit at my exams every time =U Thankfully by bull is enough to get me a passing grade XD
Hmm.. What chapter of Maths do you want exercises from? O:

I think we learn it as BODMAS instead of PEMDAS.
Well, I did. If I'm remembering right.
This makes me happy. I was in the Crayon Club.

I'm embarrassed. I should have thought this out a little harder before voting :(
The answer is 42, I don't see why this is so hard.
Is this really an issue dividing the internet community? REALLY?
Drats, I was defeated again.
I'm embarrassed. I should have thought this out a little harder before voting :(
Don't worry more than 600,000 ppl voted 1 (in link i gave above). Even lots of "scientific" calculators will give 1
9
Honestly that's probably cause people don't input it right/they're not programmed for that kind of operation.

Thanks Algebra, teach me something without giving a crucial step.
Try combining those with graph equations.
Becuase when I'm doing a graph in real life, I totaly will have several blank fields to include in my calculations.

refresh, i posted the answer. :P
2x + 9 = 17
2x = 8
…
then you insert that value for x into 3x - y = 5
woohoo math i can actually do
i got Fire-Fist's question wrong, though. :( forgot about the left-to-right rule.

It's 9 dammit.
I will be honest. When I first looked at it the answer that comes to mind is 1.
But after calming down I realized it's 9.
Look like I have gotten quite dull.
The parenthases are what made me fail x)
It makes it look like there are only 2 terms. Maybe because there's the division symbol and not the multiplication symbol.

haha, sorry.
[hide]Just remember that you want to isolate the unknown variables, like x and y.
So for 2x + 9 = 17
You bring the 9 over: 2x = 17 - 9
2x = 8
=> x = 4
then you insert this value for x into 3x - y = 5
3(4) - y = 5
12 - y = 5
Bring y and 5 over to the opposite sides:
12 - 5 = y
y = 7[/hide]

Oh, I think I got it….
when there is + you must subtract.
...right? RIGHT?

Yes, you can! It's easy! Lemme remind you this stuff:
3x -y = 5
… Wait this is wrong. 0.o You need a y equation since it's a system... checks site she stole it from Ah. Here it is:
x + y = 11
3x - y = 5
Yeah. First you pick which one you want to solve it with: x or y using the first equation for that. Either one is ok. If you pick x, the equation will turn into:
x + y = 11
=> 11 - x = y
If you pick y it'll be
=> 11 - y = x
Now you pick one of the the above and you put it in your second equation as in:
Let's pick the one that equals y.
3x - y = 5
=> 3x - (11 - x) = 5
=> 3x - 11 + x = 5 ( - changes into + cuz - and ( - ) turns into +
we pick here the known and unknown numbers and so we have:
=> 3x + x = 5 + 11 (since -11 changes sides it turns into +)
=> 4x = 16
=> x = 16/4
=> x = 4
Tadaaa! 8D (hoshiz I remember this crap?!)
Second one:
2x +9= 17
2x = 17 - 9
2x = 8
x = 8/2
x = 4
(this one I came up with XD)
Ok, I think I got it.
Pls gimme another exercise! THIS TIME I CAN DO IT!
BRING IT ON

Who cares ? It's only logical.
Nami,
[hide]2x + 9 = 17
-9 -9 (subtract 9 from each side)
2x = 8
–- ---
2 2 (Divide each side by 2)
x=4
...
Like Trapped said, then you insert that value for x into 3x - y = 5
so, 3(4)-y=5
12-y = 5
-12 -12 (subtract 12 from each side)
-y=-7
Invert y because it's negative.
y=7
Easy as pie.[/hide]
EDIT: Beaten yet Again!
Try this one:
y^2 - 3y + 2
y^2 + 7y - 18
Or
x^2 + 7x + 10/x+5
X (times)
2/x+2
Ok, I think I got it.
Pls gimme another exercise! THIS TIME I CAN DO IT!

Solve:

OK >_<
5x+ 3y = 7 /-3y
5x = 4y….. WAIT. What do I do with the y? ;;

I always think "6÷2(1+2)= ???" is an awkward way of writing division.
I think this is more proper:

IT MAKES LIFE EASIER.
Honestly, my entire math project report would've been 10 times messier without this.
As in… 3x - y = 5 or 2x + 9 = 17 ?
