Study Notes
Key Concepts of Boolean Algebra
- Variable: A symbol that represents a logical quantity, essential in Boolean expressions.
- Complement: The inverse of a variable, denoted by an overbar, representing the opposite truth value.
- Boolean Addition: Functions as the OR operation, combining values to achieve a true outcome if any variable is true.
- Boolean Multiplication: Represents the AND operation, where the result is true only if all involved variables are true.
Commutative and Associative Laws
-
Commutative Laws:
- For addition (OR operation): A + B = B + A, demonstrating order independence in ORing variables.
- For multiplication (AND operation): A . B = B . A, highlighting that the order of ANDing does not affect the outcome.
-
Associative Laws:
- For addition: A + (B + C) = (A + B) + C, indicating grouping does not affect the result when ORing.
- For multiplication: A(BC) = (AB)C, showing that grouping in ANDing does not influence the final result.
Distributive Law
- Distributive Law: Expressed as A(B + C) = AB + AC. This states that combining OR and AND operations follows a distributive pattern, allowing for simplification of expressions involving multiple variables.
