its 6 / 2 x (1+2)
We first solve the ( ), then we solve the x which means multiplication and then the / which means division, its 100% = 1. Any other answer that is not 1 its completely wrong because im studying Civil Engineering, please go back to high school!

PD: The (1+2) its multipliying the 2 which is dividing the 6... in other words its actually like this

6
------
2(1+2)

If its not like this, then who planted the problem is not right, if you meant:

6
-- (1+2) should be like this 6/2 (1+2) (hope you can notice the space between 6/2 and (1+2)
2

You can check what im saying using wolfram alpha Smile  


when i typed 6/2 times (1+2) on wolfram alpha, i got 9 o.o  


Wolfram Alpha doesnt recognize what im saying btw, just tested it
try
6/(2(2+1) and the answer is 1. The problem of this isnt the order, if you start first with division or multiplication, who is multiplying the (2+1), which in this case, the picture is saying that (2+1) is multiplying only the 2, otherwise the picture should have a space between the 2 and the (2+1).

Future engineer here...

The issue I see is how vague the problem is. It can be interpreted as [A] (6/2)*(2+1) or y*z where y = (6/2) and z = (2+1) OR it can be interpreted as [B] 6/(2(2+1)) or 6/2z where z = (2+1).

If you take it as A, then the order of operations entails that you divide first, and so the answer is 3*(2+1) = 3*3 = 9. If you take it as B, then (2+1) is being multiplied by 2 just like in the algebraic equation of 2x, x is also being multiplied by 2. So the answer is 6/(2*3) = 6/6 = 1.

So, really, it depends on how you look at it. It can be either or UNLESS it is laid out on paper in proper fractional form.


Edit: my noob-*** messed up the picture. Fixed.

The answer is one.

Follow the rules

(2+1) = 3 * 2 = 6 / 6 = 1

well yes the answer is one.

follow PEMDAS (parenthesis, exponent, * , / , + , -) and from left to right.

therefore:
-> 6/2(1+2)= x
-> 6/2(3) = x
-> 6/6 = x
= 1

Ok enough is enough. It's 9

Ok I'm going to show you how.

6/2(1+2)=?

PEMDAS

Do P first.

6/2(3)=?

Then E and their isn't any then you do order of operation left from right. So It can be M Or D depending which one comes first. Yes M is first but it is a math rule that you can switch it up depending on the order of operation and which one comes first.

3(3)=?

Then 3 x(3) Basically what it means and the answer is 9

So those who said 9 is correct. Those who did 1 was incorrect BUT just forgot that one step.

6/2*(1+2)=x
6/2*3=x
3*3=9
