What are the logical connectives and symbols?
A Logical Connective is a symbol which is used to connect two or more propositional or predicate logics in such a manner that resultant logic depends only on the input logics and the meaning of the connective used. If and only if (⇔).

How are connectives used to connect two logics?
A Logical Connective is a symbol which is used to connect two or more propositional or predicate logics in such a manner that resultant logic depends only on the input logics and the meaning of the connective used. Generally there are five connectives which are −. OR (∨) AND (∧) Negation/ NOT (¬) Implication / if-then (→) If and only if (⇔).
How to apply logic to a mathematical statement?
In order to apply the laws of logic to mathematical statements, you need to understand their logical forms . If you take a course in mathematical logic, you will see a formal discussion of proofs.
