Proof step 2 from proof mod-gcd-01 (previous step)

⊦ i % gcd(i, j) = 0, j = 0

User applied rule insert lemma

And obtained the following new goals

Proof step 3:
⊦ i ≠ 0 → i % gcd(i, j) = 0
Proof step 4:
j ≠ 0 → j % gcd(j, i) = 0 ⊦ i % gcd(i, j) = 0, j = 0

Rule argument

spec: int-gcd inst: name: mod-gcd seq: ⊦ i ≠ 0 → i % gcd(i, j) = 0 subst: [i, j] → [j, i] flags: current, []
