Key Topics to Revise
1
Statements and Truth Values
- A statement is a declarative sentence that is either true or false, but not both simultaneously
- Truth value: T for true statements, F for false statements
- Open sentences are not statements as their truth depends on unknown variables
2
Logical Connectives and Truth Tables
- Five main logical connectives: ∧ (and), ∨ (or), ~ (not), → (if-then), ↔ (if and only if)
- Conjunction (p ∧ q): True only when both p and q are true
- Disjunction (p ∨ q): False only when both p and q are false
3
Quantifiers and Quantified Statements
- Universal quantifier (∀): 'for all' or 'for every'
- Existential quantifier (∃): 'there exists' or 'for some'
- Quantified statements convert open sentences into statements
4
Statement Patterns and Logical Equivalence
- Statement patterns use variables p, q, r for simple statements
- Two patterns are logically equivalent if they have identical truth values
- Written as p ≡ q for equivalent patterns
