Answer:
Negation
- Negation. Sometimes in mathematics it's important to determine what the opposite of a given mathematical statement is. This is usually referred to as "negating" a statement. 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).
Conjunction
- A conjunction is a statement formed by adding two statements with the connector AND. When two statements p and q are joined in a statement, the conjunction will be expressed symbolically as p ∧ q. ... If both the combining statements are true, then this statement will be true; otherwise, it is false.
Disjunction
- A disjunction is a compound statement formed by joining two statements with the connector OR. The disjunction "p or q" is symbolized by p q. A disjunction is false if and only if both statements are false; otherwise it is true. The truth values of p q are listed in the truth table below.
Conditional
- A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences. For this conditional statement, P is called the hypothesis and Q is called the conclusion. Intuitively, “If P then Q” means that Q must be true whenever P is true.
Biconditional
- 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".
