What is a contra positive statement?
Conditional statements are also called "if-then" statements.One example: "If it snows, then they cancel school."The converse of that statement is "If they cancel school, then it snows."The inverse of that statement is "If it does not snow, then they do not cancel school.The contrapositive combines the two: "If they do not cancel school, then it does not snow."In mathematics:Statement: If p, then q.Converse: If q, then p.Inverse: If not p, then not q.Contrapositive: If not q, then not p.If the statement is true, then the contrapositive is also logically true. If the converse is true, then the inverse is also logically true.

How can the statement "p implies q" be expressed in an equivalent form using the logical operator "or" and the negation of "p"?

What is the negation of a conditional statement called?
The negation of a conditional statement is called the "inverse." In formal logic, if the original conditional statement is "If P, then Q" (P → Q), its negation is expressed as "It is not the case that if P, then Q," which can be more specifically represented as "P and not Q" (P ∧ ¬Q). This means that P is true while Q is false, which contradicts the original implication.
Is the conditional the negation of the Converse?
No, the conditional statement and its converse are not negations of each other. A conditional statement has the form "If P, then Q" (P → Q), while its converse is "If Q, then P" (Q → P). The negation of a conditional statement "If P, then Q" is "P and not Q" (P ∧ ¬Q), which does not relate to the converse directly.
What of a statement P would be written in the form not P?
The statement "not P" is the negation of statement P. It means the opposite of P is true. For example, if P is "The sky is blue," then not P would be "The sky is not blue."
Can you explain the difference between the keyword "p" and "not p"?

Is The inverse is the negation of the converse?
No, the inverse is not the negation of the converse. Actually, that is contrapositive you are referring to. The inverse is the negation of the conditional statement. For instance:P → Q~P → ~Q where ~ is the negation symbol of the sentence symbols.

What notation does a condition statement use?
"if p then q" is denoted as p → q. ~p denotes negation of p. So inverse of above statement is ~p → ~q, and contrapositive is ~q →~p. ˄ denotes 'and' ˅ denotes 'or'
