  1. I've never encountered that, ever.... not even right through to completing a mathematics degree at university. Maybe I was lucky with teachers? A more likely reason would be that students misunderstand what they're taught. A glaring example is the PEMDAS / BODMAS thing and not paying attention to detail. The acronym is a guide. It's not a full set of rules, but people seem to forget that.

  2. They're correct for the intended purpose , and that purpose is to jog one's memory. PEMDAS is not a full set of rules. We were taught that in full detail. Luckely, I had a few excellent teachers. Studenrs are supposed to remember details such as M and D have equal precedence.

  3. ​ @HeinrichDixon Why do you think people get it wrong? Are they poorly taught? It's a pretty simple concept.

  4. Yeah, there are a few variations, but all mean the same thing. The most common problem seems to be people forgetting to work left to right when there are an Ms and Ds. They wrongly follow the PEMDAS order.
