9. Axiom #5 : Identity Element B has identity elements with respect to + and * 0 is the identity element for +, and 1 is the identity element for * a + 0 = a and a * 1 = a Axiom #6: Distributive * is distributive over + and + is distributive over * a * (b + c) = (a * b) + (a * c), and a + (b * c) = (a + b) * (a + c) Axiom #7: Complement Element For every a in B there is an element a' in B such that a + a' = 1, and a * a' = 0

11. Basic Gates and Functions Logic gates AND , OR , NOT , NAND , NOR , EXOR and EXNOR

12. AND gate

13. OR gate

14. NOT gate

15. The diagrams below show two ways that the NAND logic gate can be configured to produce a NOT gate . It can also be done using NOR logic gates in the same way .
