the product of two integers is odd if and only if the two factors are odd
It is the biconditional.
the statement IFF means "if and only if"
The area of a square is 25 square meters if and only if the side length of the square is 5 meters
false
Wingman principles apply only while on duty.
a condtional statement may be true or false but only in one direction a biconditional statement is true in both directions
No, not always. It depends on if the original biconditional statement is true. For example take the following biconditional statement:x = 3 if and only if x2 = 9.From this biconditional statement we can extract two conditional statements (hence why it is called a bicondional statement):The Conditional Statement: If x = 3 then x2 = 9.This statement is true. However, the second statement we can extract is called the converse.The Converse: If x2=9 then x = 3.This statement is false, because x could also equal -3. Since this is false, it makes the entire original biconditional statement false.All it takes to prove that a statement is false is one counterexample.

Definition
A biconditional is the conjunction of a conditional statement and its converse.
The symbol for a biconditional statement is typically represented as "↔" or "⇔". It indicates that two propositions are equivalent, meaning that both are true or both are false. In logical terms, a biconditional can be expressed as "P if and only if Q," suggesting that P is true exactly when Q is true.
What is negation of biconditional statement?
The converse of the given conditional statement "If tomorrow is Monday, then today is a weekend day" is "If today is a weekend day, then tomorrow is Monday." This converse is not necessarily true, as today could be Saturday or Sunday, but not both leading to Monday. A valid biconditional statement that reflects the original conditional could be "Today is a weekend day if and only if tomorrow is Monday." However, this biconditional is also false since today could be Sunday with tomorrow as Monday, but Saturday does not lead to Monday.
The term that refers to an "if and only if" statement is "biconditional." In logic, a biconditional statement asserts that two statements are equivalent, meaning that both must be true or both must be false for the biconditional to hold true. It is often represented using the symbol "↔" or phrases like "p if and only if q" (p ↔ q).

When a conditional statement and its converse are both true, they can be combined to form a biconditional statement. A biconditional statement asserts that both the original condition and its converse are true simultaneously, typically expressed in the form "P if and only if Q." This indicates that P is true exactly when Q is true, establishing a strong logical equivalence between the two.
