Statements that are always logically equivalent are those that yield the same truth value in every possible scenario. Common examples include a statement and its contrapositive (e.g., "If P, then Q" is equivalent to "If not Q, then not P") and a statement and its double negation (e.g., "P" is equivalent to "not not P"). Additionally, the negation of a statement is logically equivalent to the statement's denial (e.g., "not P" is equivalent to "if not P, then false"). These equivalences play a crucial role in logical reasoning and proofs.

Not always. For example, X is equal to or less than 6 is not the same as X is equivalent to 6.
Which statement always has the same truth value as the conditional?
The statement "if not p, then not q" always has the same truth value as the conditional "if p, then q." They are logically equivalent.
