Study Notes
Laws of Boolean Algebra
-
Idempotent Laws:
- A or A = A: Repeating an operand in an OR condition does not change the outcome.
- A and A = A: Repeating an operand in an AND condition retains the operand.
-
Commutative Laws:
- A or B = B or A: Order of operands does not affect the result in OR operations.
- A and B = B and A: Order of operands does not affect the result in AND operations.
-
Associative Laws:
- A or (B or C) = (A or B) or C: Grouping in OR operations does not affect the outcome.
- A and (B and C) = (A and B) and C: Grouping in AND operations remains unchanged.
-
Distributive Laws:
- A and (B or C) = (A and B) or (A and C): AND distributes over OR.
- A or (B and C) = (A or B) and (A or C): OR distributes over AND.
-
Laws of Union and Intersection:
- A or true = true: Any operand ORed with true results in true.
- A and false = false: Any operand ANDed with false results in false.
-
Law of Absorption:
- A and (A or B) = A: An AND operation absorbs ORed terms if one of the operands is the first term.
- A or (A and B) = A: An OR operation absorbs ANDed terms if one of the operands is the first term.
-
Identity Elements:
- A and true = A: True acts as the identity element in AND operations.
- A or false = A: False acts as the identity element in OR operations.
-
Double Negative Law:
- !(!A) = A: Negating a negation returns the original operand.
-
Complement Laws:
- A or !A = true: An operand ORed with its complement results in true.
- A and !A = false: An operand ANDed with its complement results in false.
-
DeMorgan's Laws:
- !(A or B) = !A and !B: The negation of an OR statement becomes the AND of their negations.
- !(A and B) = !A or !B: The negation of an AND statement becomes the OR of their negations.
