Biconditional Biconditional is the logical connective corresponding to the phrase “if and only if”. An example: Alice will forgive Bob if and only if he apologizes to her. Obviously “p if and only if q” contains two sentences – “If q, p” and “Only if q, p”.As we have seen, by “only if” we form a conditional whose consequent is the sentence after “only if”, so “Only ...

In logic and mathematics, the logical biconditional, sometimes known as the material biconditional, is the logical connective () used to conjoin two statements P and Q to form the statement "P if and only if Q", where P is known as the antecedent, and Q the consequent. This is often abbreviated as "P iff Q". Other ways of denoting this operator may be seen occasionally, as a double-headed …

In logic and mathematics, statements and are said to be logically equivalent if they are provable from each other under a set of axioms, or have the same truth value in every model. The logical equivalence of and is sometimes expressed as , , , or , depending on the notation being used. However, these symbols are also used for material equivalence, so proper interpretation would depend on the context. Logical equivalence is different from material equivalence, although the t…

13.02.2018 · A biconditional can also be stated as "P is equivalent to Q," whereas a logical equivalence can also be stated as "P is logically equivalent to Q." I never understood intuitively what the difference between them was. I get that biconditional is true when both P and Q are true or false, and logical equivalence means P and Q have all of the same ...

16.09.2018 · Since B is a necessary condition for A (recall from the truth table for implication that if B is true, A must also be true), we can claim that !B → !A. (A → B) === (!B → !A) Material Equivalence. The name biconditional comes from the fact that it represents two conditional (implication) statements: A === B means that A → B and B → A.

Conditional and BiConditional Statements Conditional Statement. Let p and q are two statements then "if p then q" is a compound statement, denoted by p→ q and referred as a conditional statement, or implication. The implication p→ q is false only when p is true, and q is false; otherwise, it is always true.
