👉 The either math, also known as the law of excluded middle or principle of bivalence, is a fundamental concept in classical logic and mathematics that states for any proposition \( P \), either \( P \) is true or its negation \( \neg P \) is true. This principle asserts that a statement cannot be both true and false simultaneously within a given logical framework, thus eliminating any middle ground or ambiguity. This binary approach simplifies reasoning and decision-making processes but can be challenged in contexts involving vagueness, uncertainty, or multi-valued logic systems.
