- 1StatementA complete sentence that asserts a a claim that is either true or false but not both at the same time.
- 2ParadoxA sentence that contradicts itself and therefore has no single truth value.
- 3NegationIt is the logical opposite of a statement, or its denial.
- 4Compound statementComposed of two or more statements joined together using connective words such as and, or, or implies.
- 5Truth TableA table that has a row for each possible combination of truth values of the individual statements that make up the compound sentence

T when each statement have the same truth value (both true or false) - 10Logically Equivalent Statements≡
Statements that have exactly the same truth values in all situations - 11Converse of a conditional statementq => p
- 12Inverse of a conditional statement~p => ~q
- 13Contrapositive of a conditional statement~q => ~p
- 14Negation of a conditional statement~ (p => q) = p ^ ~q
- 15De Morgan's Laws~ (p ^ q) = ~p v ~q
~ (p v q) = ~p ^ ~ q - 16Ways to convey p => q Phrases used to say a conditionalp implies q / if p, then q
p is sufficient for q / p only if q
q is necessary for p / q if p
p will lead to q / q whenever p
