Symbol Name | Explanation | Example |
---|---|---|

P ↑ Q | Negation of conjunction ( nand ) | P ↑ Q ≡ ¬ ( P ∧ Q ) |

P ↓ Q | Negation of disjunction ( nor ) | P ↓ Q ≡ ( ¬ P ∧ ¬ Q ) |

P → Q | Conditional (If , then ) | For all , P → P is a tautology. |

P ↛ Q | Non-conditional (Not ‘if , then ‘) | P ↛ Q ≡ P ∧ ¬ Q |

Negation of a Conditional By definition, p → q is false if, and only if, its hypothesis, p, is true and its conclusion, q, is false. It follows that the negation of “If p then q” is logically equivalent to “p and not q.”

The negation of a conditional statement is only true when the original if-then statement is false. The negation of a conjunction is only false when the original two statements are both true. A conjunction is two statements that are joined by an “and”.

One thing to keep in mind is that if a statement is true, then its negation is false (and if a statement is false, then its negation is true)….Summary.

Statement | Negation |
---|---|

“For all x, A(x)” | “There exist x such that not A(x)” |

“There exists x such that A(x)” | “For every x, not A(x)” |

To negate a conditional statement, you have to realize that what you’re negating is the conditional relationship. In other words, where the original statement says that A and B exist in a conditional relationship, you’re saying that no, A and B do not exist in a conditional relationship.

A conditional statement is false if hypothesis is true and the conclusion is false. The example above would be false if it said “if you get good grades then you will not get into a good college”. If we re-arrange a conditional statement or change parts of it then we have what is called a related conditional.

A conditional statement is logically equivalent to its contrapositive. Converse: Suppose a conditional statement of the form “If p then q” is given. The converse is “If q then p.” Symbolically, the converse of p q is q p.

There are following types of conditional statements in C.

- If statement.
- If-Else statement.
- Nested If-else statement.
- If-Else If ladder.
- Switch statement.

Conditional statements are sentences that have the form “If…, then….” A conditional statement asserts that if something is true, then something else would be true also.

What is Conditional Reasoning on the LSAT? A basic conditional statement has two conditions: the sufficient condition and the necessary condition. The sufficient condition is a statement that is sufficient information to indicate that the necessary condition necessarily occurs or occurred.

Can a conditional statement express a fact or a certainty? No, conditional statements do not state facts. …
