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 :)
It's actually "both". There are two conventions. One is a bit more popular in science and engineering and the other one in the general population. It's actually even more complicated than that (thus the long blog post) but the most correct answer would be to point out that the implicit multiplication after the division is ambiguous. So it's not really "solvable" in that form without context.
You’d think we would’ve solve this with Einstein or Aristotle or something.
It's not a math problem, it's a communication problem. The person who wrote it down didn't make themselves clear
