Oh yes so so true, exellent Mr D.

These one's always crack me up. The identity law especially.

T1 : Commutative Law
(a) A + B = B + A
(b) A B = B A

T2 : Associate Law
(a) (A + B) + C = A + (B + C)
(b) (A B) C = A (B C)

T3 : Distributive Law
(a) A (B + C) = A B + A C
(b) A + (B C) = (A + B) (A + C)

T4 : Identity Law
(a) A + A = A
(b) A A = A

[Tigerrrr.......]

Your T3 (b) isn't right.

Sorry!
