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 :)
This is a very nice piece that had so much information I did not know. Toward the top of the article I was wishing for footnotes, references or something that would indicate it was not just your opinion, but as I got further into the piece you provided so many great references. I thought the calculator manuals were particularly accessible and convincing. Thanks for a great read!
Except for any actual Maths textbooks. Try this instead.
