  1. p q r Propositions: Statements either true false or indeterminate

  2. ⇒ then statement p ⇒ r If p then r If p is true r is true if p is false r is false if p is indeterminate then r is indeterminate

  3. ⇔ equivalence statement p ⇔ r p equals r If p is true r is true If p is false r is false If p is indeterminate then r is indeterminate

  4. ¬p negation of proposition

  5. p ∧ q • Conjuction • (= and) • Similar to intersection set theory

  6. p ∨ q • Disjunction • (= pr, possibly both) • Similar to union symbol set theory

  7. p ⊻ q • Exclusive disjunction • (= or but NOT both) • One or the other never both
