Proof step 7 from proof div-mult-ls (previous step)

j0 < j, (i * i1 * j + i * j0) / j < i * i1, 0 ≤ i, 0 < j, 0 ≤ j0, 0 ≤ i1 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-div inst: name: div-add1-pospos seq: ⊦ i % j = 0 ∧ 0 ≤ i ∧ 0 ≤ i0 ∧ 0 < j → (i + i0) / j = i / j + i0 / j subst: [j, i0, i] → [j, i * j0, i * i1 * j] flags: rewrite, current
