that is one of the most poorly written wikipedia articles i have ever read

  Contrast with https://en.wikipedia.org/wiki/Digital_root https://en.wikipedia.org/wiki/Digital_root which presents much of the same material and is a decent fully-wikified article using math notation. I think the casting out nines article could be improved a lot, maybe with more of a focus on the history of the concept.

    I suspect the average non-mathematician would get a lot more out of the "Casting out nines" page than the "Digital root" page.

      Sure, it's definitely helpful to have a less-technical article.

  Seriously ... I had to go all the way to "Further Examples" just to get any idea what it was talking about.
