What is a bicondional?

Answer 1

A biconditional is a logical statement that asserts two propositions are equivalent, meaning both must be true or both must be false for the statement to hold true. It is often expressed using the phrase "if and only if" (often abbreviated as "iff"). For example, a biconditional statement could be "A is true if and only if B is true," indicating that A and B are linked in such a way that the truth of one guarantees the truth of the other. In formal logic, biconditional statements are typically represented by the symbol ↔.
