Study Notes
Logical Operations in Propositional Logic
-
Negation (¬p)
- Represents "It is not the case that P" or "Not P."
- Changes the truth value of proposition P to its opposite.
-
Conjunction (p ∧ q)
- Denotes "P and Q."
- The statement is only true when both P and Q are true.
Truth Conditions for Logical Operations
-
Disjunction (p ∨ q)
- Indicates "P or Q."
- This operation is only false when both P and Q are false.
-
Exclusive Or (p ⊕ q)
- Described as "Either P or Q, but not both."
- The outcome is true when one of them is true (TF or FT) and false when they share the same truth values (TT or FF).
Implications and Equivalences
-
Conditional Statement (p → q)
- Represents "If P then Q."
- This statement is false only when P is true and Q is false (TF).
-
Biconditional Statement (p ↔ q)
- Expresses "P if and only if Q."
- True when both P and Q have the same truth values, either both true (TT) or both false (FF).
