The symbol in logic represents negation, indicating the opposite or denial of a statement. It is used to express the concept of "not" in logical propositions.

Negation is in its fundamental definition the opposite of "true", so let us say you had F and F would be 5, you could see 4 as the negation of F as it is "not F" because the statement that 4 is F is "false" in this case.

You can think of the minus sign as the negation operator in symbolic logic. Take a positive number, for example 5. Negate it one to get -5, then, following the rule from logic that a double negation is the equivalent to doing nothing at all, --5=5. The same goes for any number x.
The rule of double negation states that if a statement is negated twice, it is equivalent to the original statement. In formal logic, this can be expressed as ¬(¬P) = P, where "¬" represents negation. Essentially, removing two negations leads back to the affirmative form of the proposition. This principle is often used in logical reasoning and proofs to simplify expressions.
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.
