    That means that they gave us that information in the book, and I have to complete the proof using that information. It's like the "given."

    S -> ~T = 1 when S=0 and T = 1, 0; and when S=1 and T=0 T = 1; so S = 0 ~S -> R = 1 -0 -> R = 1 when R = 1

    Premise means it is given. It is presumed to be true.

    S -> -T 1 -> 0 = 0 1 -> 1 = 1 0 -> 0 = 1 0 -> 1 = 1 T = 1 0 -> 0 = 1 -S -> R 1 -> 0 = 0 1 -> 1 = 1
