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 :)
We can also say x=(1+2) and now we read 6/2x and I can guarantee that not a single person with a mathematical background will look at that and think (6/2)x rather than 6/(2x)
