Of course the answer is 9. But my question is, some sources say this is written ambiguously.
as in, 6/(2[1+2])=1
or 3(3)=1
Why do some people say one needs to evaluate what is effecting the parenthesis before dividing from left to right? I don't see anything in order of operations that would assume the first option. But when you type 6/2(1+2) into some calculators, it gives you 1. Can anybody find a source that says one needs to evaluate what is effecting the parenthesis before dividing from left to right?

This has been covered over and over and over. This is not physics. Reported.
