I wrote a (very long) blog post about those viral math problems and am looking for feedback, especially from people who are not convinced that the problem is ambiguous.
It's about a 30min read so thank you in advance if you really take the time to read it, but I think it's worth it if you joined such discussions in the past, but I'm probably biased because I wrote it :)
The problem with BODMAS is that everybody is taught to remember "BODMAS" instead of "BO-DM-AS" or "BO(DM)(AS)". If you can't remember the order of operations by heart you won't remember that "DM" and "AS" are the same priority, that's why I suggested dropping "division" and "subtraction" entirely from the mnemonic.
It's true that calculators also don't dictate a standard but they implement what conventions are typically used in practice. If a convention would be so dominating (let's say 95% vs 5%) all calculator manufacturers would just follow the 95% convention, except maybe for some very special-purpose calculators.
In fairness, I did quite like the suggestion to just remove division and subtraction! One that should be taken to heart :)
