The youtube link has this same problem with different numbers. If you cant follow it and substitute the numbers from the OP's problem in for yourself you probably shouldnt be participating. Ill break it down for you tho anyway.
In the video:
48÷2(9+3)
48=a
2=b
9=c
3=d
a÷b(c+d)
now the OPs numbers...
6=a
2=b
1=c
2=d
6÷2(1+2)
Same concept, same process. Answer is 9
if that doesnt clear it up for ya then i dont know what to tell ya
Edit: and if you are referring to the other link, that was just to illustrate that multiplication and division are performed left to right at the same time... before any addition and subtractionedit on 2-5-2011 by ASeeker343 because: clarification
holy cow you jump right into "i shouldn't be participating" ???
really? what youtube video? i didn't view any video ... i was responding to the nonsense spewing here.
i guess i may go looking for the video just so i can respond to whatever nonsense this is ... care to share which page i might find it?
as for the other link, i was referring to it because the rule changes when parenthesis appear ... left to right goes out the window as well as sequencing based on the location of the parenthesis ... basic algebra.
EX: if the only parenthesis indicate an addition problem, you will perform it before any other.
If the parenthesis indicate the multiplication of a root ... first, you must find the root, not do the multiplication.
yes, the problem is poorly written, however, As it is written, the answer is only "1".

Are you telling me that 6/2(3) is different than 6/2*3? If so i would disagree

ummmm, where did this come from and no i didn't say such a thing, besides ... your 6/2*3 uses symbols before my time. it isn't an equation we would have seen back then. however, if you think 6/2*3 is the same as 6 divided by 2(2+1), you are sadly mistaken.

don't need a link ... the problem speaks for itself
let's try this instead ... 6 / 2(2+1)
= 6 / (2+1)+(2+1)
= 6 / (3)+(3)
= 6 / (6)
= 1
better? you must define the equation before solving it, period.
parenthesis give direction, always. As for left to right, the division of the left is performed last.
as for sequencing via PEMDAS ... that is why the P is always first.
No offense taken and none intended but i learned math long before computers or calculators existed.

6/2 = 6*(1/2)
6*(1/2)*(1+2)
Following the order of operations...
6*(1/2)*(3)
(6/2)*(3)
3*3 = 9.
I thought this nonsense could only stump people on Facebook and the like. Disgusting.

we agree on the stuff inside the parentheses: (2+1) = 3
good start
6÷2(1+2)
6÷2(3)
What I am saying is that the 2(3) does not put the multiplication before the division. 6÷2(3) = 6÷2x3.
Left to right. Parentheses state the argument inside them must be performed first, not anything adjacent as well. If you can provide me with solid proof otherwise ill eat crow but otherwise, 6÷2x3 = 9 Left to right.

ok, so my english is off but my math is not.

2(2+1) is NOT an equation.
It is an expression.

bad math? did the rule of distribution disappear or something?
algebra was an awfully strong subject of mine and i don't think it's changed that much over the years.
