Logic ∼p not p 25
p∧q p and q 25
p∨q p or q 25
p ⊕ q or p XOR q p or q but not both p and q 28
P≡Q P is logically equivalent to Q 30
p→q if p then q 40
p↔q p if and only if q 45
∴ therefore 51
P(x) predicate in x 97
P(x) ⇒ Q(x) every element in the truth set for P(x) is in 104
the truth set for Q(x)
P(x) ⇔ Q(x) P(x) and Q(x) have identical truth sets 104
∀ for all 101
∃ there exists 103
