Hi, I found this problem in my university page in facebook. The problem is this 6/2(1+2)=? Using the PEMDAS method, I came to the answer that it is 1.. But there's a professional from the page saying that the right answer is 9. She says that division comes first before multiplication. Help! I need to clarify what the true answer is before my head bursts out of confusion. Thank you very much.

6 ÷ 2(1 + 2) = 6 ÷ 2(3) = 3(3) = 9

Why is it you need to divide first the number 6 to 2? Am I right when I say that we can express the problem in a rational form the numerator is 6 and denominator is 2(1+2) simplifying getting an answer of 1?

PEMDAS, PEDMAS, PEMDSA or PEDMSA works, i.e. from left to right.
