# 07 - Identity and Idempotent laws

1. What law? A + A = A

Idempotent (OR)

Identity

Commutative

Anunulment

2. What law? A. A = A

Identity

Commutative

Idempotent (OR)

Idempotent (AND)

3. Fill in the blanks for A, B and C in the following simplification example.

A, B, C = Identity

A, B = Identity and C = Indempotent

A =Idempotent B = Identity C = Identity

A = Distributive B = Identity C = Idempotent

4. What law? A + 0 = A

Commutative

Identity

Idempotent (AND)

Idempotent (OR)

5. What law? A.1 =A

Identity

Idempotent (OR)

Idempotent (AND)

Commutative

6. A term OR´ed with a “0” or AND´ed with a “1” will always equal that term. This is the ________________ law

Identity

Idempotent (OR)

Commutative

Idempotent (AND)

7. A variable AND’ed with itself is always equal to the variable

Idempotent (OR)

Idempotent (AND)

Commutative

Identity

8. A variable AND’ed with 1 is always equal to the variable

Idempotent (OR)

Commutative

Idempotent (AND)

Identity

9. The order in which two variables are AND’ed makes no difference

Idempotent (OR)

Commutative

Identity

Idempotent (AND)

10. In the following step by step simplification, fill in the blanks for 'A' and 'B'.

A = Idempotent B = Identity

A and B are both = Identity

A and B are both = Idempotent

A = Identity B = Distributive
