6/2(1+2) = ?

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?
