    Hello,

    When your DD is -1 and you add 11 to take care of a negative I assume 10 is as far as you go. Otherwise, you get -1 again over and over. An example id DD of 54 is -1 -> add 11 to get 10 -> change to a single digit you get -1 and on and on.

    Is my assumption correct or am i missing a rule?

    Also I’m assuming 10 is equal to 0 for DD and that you do not ignore 9’s.
