    A very simple question that's alluding me.
    How is it that ~B+A~BD = ~B ?

    If the first term is True, does the second term matter?

    If the first term is False, can the second term be True?

    Can you factor out any common factors in those two terms?

    If so, what is left?

    Ah,
    ~B(1+AD)
    ~B(1)
