Need Serious Math help, 6÷2(1+2)=? Look at description please

ok so yesterday i was on facebook, and facebook made these little questions that turn into polls.

so it says "6÷2(1+2)=?" it gives us for 2 answers...

A. 1
B. 9

so im pretty positive that the answer is 1.. because of pemdas, correct?
i showed my calculus teacher to make him have a good laugh.. but after he immedietly gets 1, another student says that he got 9.. and now my calculus teacher believes it 9...

on facebook.. about 350,000 ppl answered 9
and only like 220,000 answered 1

either 9 is correct.. and i have lost my mathematical reasoning, or my teacher made an error....

plz help meeeeeeeeeeee, im so confused... lol

i do give best anwsers..

Everyone who answered 9 is CORRECT, although ¢-яσ∂ '94♥ seems to have stumbled onto the correct question.

Moon Rose, Athena, and Peter B give excellent explanations.

Please note that PEMDAS is NOT the only acronym for remembering order of operation. Others include:

PEDMAS: parenthesis, exponent, division, multiplication, addition, subtraction
BEDMAS: brackets, exponent, division, multiplication, addition, subtraction
BIMDAS: brackets, indices, multiplication, division, addition, subtraction
BODMAS: brackets, order, division, multiplication, addition, subtraction
BOMDAS: brackets, order, multiplication, division, addition, subtraction

where:
brackets are equivalent to parenthesis
indices/order are equivalent to exponent

So you may wonder, which is correct? THEY ALL ARE!

That's because multiplication and division have EQUIVALENT order
as do addition and multiplication.

So the correct order of operation is:

P - parenthesis
E - exponents (from right to left: 2^3^2 = 2^9 and not 8^2)
MD - multiplication/division (from left to right, in order they appear)
AS - addition/subtraction (from left to right, in order they appear)
