Biconditional or Double Implies with Truth Table

In this class, We discuss Biconditional or Double Implies with Truth Table.

The reader should have prior knowledge of conditional connectives. Click Here.

Biconditional or Double Implies:

The symbol for double implies <->.

The condition for double implies is if P then Q and if Q then P.

In our previous class, we discussed conditional connectives.

The condition implies it is if P, then Q.

From the above, we can write Biconditional as (P -> Q) ∧ (Q -> P)

The below diagram shows the truth table for Biconditional.

For better remembrance of the biconditional truth table, check the below points.

The Biconditional gives a true value if P and Q have the same truth values.

The Biconditional gives a false value if P and Q have different truth values.
