    Hi Mr. Gillespey,
    In the even or odd subsets thing, can u just divide the number of subsets by two, instead of doing 2^(n-1)

  1. Yes you can do it that way. But why multiply then divide its just more work.

    An easier way to find the amount of subsets is to multiply 2^# of elements

    1. That is true but do you know why it works?

      Its actually really cool.
