The discrete math book said this is tautology A ↓ ( A ↓ A) ≡ T . We know that ( A ↓ A) ≡ ∼ A where ↓ is the NOR symbol. so A ↓ ( A ↓ A) ≡ A ↓ ... WebA tautology is a logical statement that must be true under any and all circumstances. Mathematical proofs rely on tautologies. If they were built on statements that could be false, there would be exceptions to mathematical rules. All branches of mathematics rely on tautologies. They are especially important to logic, though.
