The addition axiom states that when two equal quantities are added to two more equal quantities, their sums are equal. Thus, if a = b and y = z, then a + y = b + z. WebJan 13, 2024 · 1. Use Armstrong’s axioms to prove the soundness of the union rule. (Hint: Use the augmentation rule to show that, if α → β, then α → αβ. Apply the augmentation rule again, using α → γ, and then apply the transitivity rule.) 2.
