Study Notes

Commutative Laws

  • States that the order of operands does not affect the result.
  • For AND operation: A ^ B = B ^ A.
  • For OR operation: A Ë… B = B Ë… A.

Associative Laws

  • Indicates that how operands are grouped does not change the outcome.
  • For AND operation: A ^ (B ^ C) = (A ^ B) ^ C.
  • For OR operation: A Ë… (B Ë… C) = (A Ë… B) Ë… C.

Distributive Laws

  • Demonstrates how AND and OR operations can distribute over each other.
  • For AND over OR: A ^ (B Ë… C) = (A ^ B) Ë… (A ^ C).
  • For OR over AND: A Ë… (B ^ C) = (A Ë… B) ^ (A Ë… C).

Idempotent Laws

  • Show that applying the same operation multiple times yields no change in result.
  • For AND operation: A ^ A = A.
  • For OR operation: A Ë… A = A.

Identity Laws

  • Define how identities for AND and OR do not alter the operand.
  • For AND operation: A ^ (A Ë… B) = A.
  • For OR operation: A Ë… (A ^ B) = A.

Complement Laws

  • Relate an operand with its complement to produce constant results.
  • For AND operation: A ^ ¬A = F (false).
  • For OR operation: A Ë… ¬A = T (true).

Involution Law

  • Explores the effect of double negation.
  • States that negating a negation returns the original value: ¬(¬A) = A.

DeMorgan's Laws

  • Transforms expressions involving negations of AND and OR operations.
  • Negation of AND: ¬(A ^ B) = (¬A) Ë… (¬B).
  • Negation of OR: ¬(A Ë… B) = (¬A) ^ (¬B).
