It's really not that big a deal that people get this wrong, the problem is deliberately written to be confusing and order of operations just isn't something that most people use on a daily basis.
If you wrote the problem
6 - (1 x 0) + (2 / 2) = ?
It would be no less complicated, and yet I'd suspect you would see a drastically higher ratio of correct answers (even despite the shockingly poor performance of our nationalized education system).

It is by caffeine alone I set my mind in motion. It is by the beans of Java the thoughts aquire speed, the teeth acquire stains, the stains become a warning. It is by caffeine alone I set my mind in motion.
Also, this is why we have parenthesis. D=
The concept that Mult/Divis are inverse forms of one another was hardly taught when I was in school, I'm sure it's not even a concept conceived of by current students. Without explicit mention in the order of operations there are going to be students who would assume that Division and Subtraction aren't bound by it or something worse.

cOur education system might perform poorly but you still hear PEMDAS and its mnemoni pretty much every year of high school. The problem isn't indicative of anything beyond that most people simply don't pay attention.
Never heard of it called that at all, Nor any mnemonic.
I learned more algabra in my chem class than actual math classes to be perfectly honest.
Graned the school system I was in also taught how to do factor trees from 3 grade on, yet vast majority of students struggled when needing to factor out equations.
I've heard there's a different mnemonic used in certain areas of the US, but I haven't found anyone that can substantiate that. Everyone either knows PEMDAS or just remembers the order explicitly.
