I didn't have very long to talk so that's why I gloss over a few details, but the overall point is still true: the (intentional) ambiguity of the mathematical statement is the real issue here. This is not really about order of operations; it's about the importance of clear communication, which is true of mathematics as much as in any other discipline.
And here is my favourite video, by @MinutePhysics, about the order of operations and the deeper issues that it raises about following rules and conventions without understanding: youtube.com/watch?v=y9h1oqv21Vs
