    show that ^ and - are complete set

    How do ^ and - make the XOR.

    using p and q I got this answer.

    p XOR q = (-(p^q)^(-p^q))^((p^-q)^-(-p^q))

    Is this the right way to write this?

    Is this not better written as:

    p xor q = not(p and q) and not( not(p) and not(q))

    table

    p q -(p^q)
    t t f
    t f t
    f t t
    f f t

    -p -q -(-p^-q)
    f f t
    f t t
    t f t
    t t f

    then

    -(p^q) -(-p^-q) and
    f t f
    t t t
    t t t
    t f f

    then yes it would thanks, that's much clearer.
