    (3×3×2)/2 = 9. A number can't start with 0 and you have to account for the repeated 2.

    I'm out at the moment but I might attempt the Joe Shmo show at some stage!

    Edit: I had to remove the hidden feature, as it was messing up the formatting of the contained text. Obviously that's some sort of bug.

    Correct!

    Yeah, the hidden formatting has issues.

    It doesn't like multiline replies, and special characters as far as I can tell..there may be others.

    As a programmer, I object to this.
