I really need help answering these question pls 

Answers are at the end of the chapter. 1. A variable is a symbol in Boolean algebra used to represent (a) data (b) a condition (c) an action (d) answers (a), (b), and (c) 2. The Boolean expression A + B + Cis (a) a sum term (c) an inverse term (b) a literal term (d) a product term 3. The Boolean expression ABCD is (a) a sum term (c) an inverse term 4. The domain of the expression (a) A and D (c) A, B, C, and D (b) a literal term (d) a product term ABCD + AB + CD + B is (b) B only (d) none of these 5. According to the associative law of addition, (a) A + B = B + A (c) (A + B) + C = A + (B+C) (b) A = A + A (d) A + 0 = A 6. According to commutative law of multiplication, (a) AB = BA (b) A = AA (c) (AB)C= A(BC) (d) A0 = A 7. According to the distributive law, (a) A(B+C) = AB + AC (c) A(A + 1) = A. (b) A(BC) = ABC (d) A + AB = A 8. Which one of the following is not a valid rule of Boolean algebra? (a) A + 1 = 1 (b) A = A (c) AA = A (d) A + 0 = A 9.
