      Asosiatif


                   (A | B) | C               = A | (B | C)                      (A + B) + C = A + (B + C)

                   (A & B) & C               = A & (B & C)                      (A * B) * C = A * (B * C)




      Identitas jumlahan dan perkalian

                   A | 0 = A                                                      A + 0 = A

                   A & 1 = A                                                      A * 1 = A





       Negasi dari negasi

                   ~ (~ A) = A                                                    – (– A) = A
