Proof step 8 from proof mod-ls-same-02 (previous step)

i < 0 ⊦ j = 0, i < i % j ↔ abs(j) = 1 ∨ ¬ 0 < abs(j) + i

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-div inst: name: mod-zero-05 seq: ⊦ abs(i) < j → i % j = i subst: [j, i] → [j, i] flags: rewrite, current
