Following are the basic postulates of Boolean algebra:
(1) If X not equal to 0 then X equal to 1; and If X not equal to 1 then X equal to 0
(2) OR Relations (Logical Addition)
(i) 0 + 0 = 0
(ii) 0 + 1 = 1
(iii) 1 + 0 = 1
(iv) 1 + 1 = 1
(3) AND Relations (Logical Multiplication)
(i) 0 . 0 = 0 (ii) 0 . 1 = 0 (iii) 1 . 0 = 0 (iv) 1 . 1 = 0
(4) Complement Rules
(i) 0’ = 1 (ii) 1’= 0
