A biconditional is a statement wherein the truth of each item depends on the truth of the other.
If a number is nonzero, then the number is positive.
A biconditional statement is a compound statement consisting of a double conditional: "She's going to the party if and only if I'm going." (I'm going if she's going and vice-versa.) Thus, it's basically the conjunction of two conditionals, where the antecedent of either is the consequent of the other.
What is negation of biconditional statement?
A biconditional is a statement wherein the truth of each item depends on the truth of the other.
It is the biconditional.
A biconditional statement, expressed as "P if and only if Q" (P ↔ Q), can be rewritten as two conditional statements: "If P, then Q" (P → Q) and "If Q, then P" (Q → P). This means that both conditions must be true for the biconditional to hold. Essentially, the biconditional asserts that P and Q are equivalent in truth value.
a condtional statement may be true or false but only in one direction a biconditional statement is true in both directions

A biconditional is the conjunction of a conditional statement and its converse.
true
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.
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).
