Proof step 3 from proof two-ppred (previous step)

⊦ m / 2 = (m - 2) / 2 + 1, m = 0, m = 1

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
n ≠ 0 ⊦ m0 = m / n ∧ n0 = m % n ↔ m = m0 * n + n0 ∧ n0 < n
Proof step 5:
m = m0 * 2 + n0, n0 < 2 ⊦ 2 = 0, m = 1, m = 0, m0 = (m - 2) / 2 + 1

Rule argument
