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 :)

  • there’s absolutely no difference in n(n-1) and n*(n-1)

    There is - the first is 1 term and the 2nd is 2 terms. Makes a difference if it’s preceded by a division.

    it’s just matter of convenience you can leave it off.

    It’s a matter of how many terms as to whether it’s there or not.
