Proof step 13 from proof range-eq-append (conclusion)

⊦ range=(ar0, n0, ar1, n1, m0 + m1) ↔ range=(ar0, n0, ar1, n1, m0) ∧ range=(ar0, n0 + m0, ar1, n1 + m0, m1)

User applied rule structural induction

And obtained the following new goals

Proof step 5:
⊦ range=(ar0, n0, ar1, n1, 0 + m1) ↔ range=(ar0, n0, ar1, n1, 0) ∧ range=(ar0, n0 + 0, ar1, n1 + 0, m1)

Rule argument

indvar: m0
