Commutation
The commutative law states that the inter-changing of the order of operands in a Boolean equation does not change its result.
- Using the OR operator → A + B = B + A
- Using the AND operator → A * B = B * A

Quick Reference
(a) A + B = B + A
(b) A B = B A
(a) (A + B) + C = A + (B + C)
(b) (A B) C = A (B C)
(a) A (B + C) = A B + A C
(b) A + (B C) = (A + B) (A + C)
(a) A + A = A
(b) A A = A
(a) 
(b) 
(a) A + A B = A
(b) A (A + B) = A
(a) 0 + A = A
(b) 0 A = 0
(a) 1 + A = 1
(b) 1 A = A
