I just hope we can all agree that anyone who arrived at 6 / 6 = 0 should not be allowed to vote lol.

Yup, that is certainly incorrect.

I'm now doubting myself on the main question, again, though.

To my example of 6/2(x+2), there's also still an argument to be made for reading it as 6/(2(x+2)), which is back to the "1" answer. In written form like that, "/" often denotes that it's treated as the preceding divided by the solution to the multiplication/division that comes after.

This video someone else linked goes into that pretty well:

I think I have to switch my answer back to "this question intentionally sucks, and that in itself is the answer." The "actual" mathematical answer doesn't really matter, since even math experts won't agree, despite the seeming simplicity. I was almost convinced of "9," but I'm back to "1" or "9" having strong arguments.
