Contraposition

Contraposition is a logical principle that involves rearranging a conditional statement. If we have a statement like "If A, then B" (where A is a condition and B is the result), contraposition allows us to restate it as "If not B, then not A." This means if the outcome does not occur (not B), then the condition must not have been met (not A). It shows a relationship between the condition and its result, emphasizing that both statements convey the same truth and are logically equivalent.
