Proof step 2 from proof mult-05 (previous step)

i0 < j, 0 < i0, 0 < j, 1 < j, 0 < i ⊦ i = (j * i - i0) / j + 1

User applied rule insert lemma

And obtained the following new goals

Rule argument

spec: int-div inst: name: mult-04 seq: ⊦ 0 < i0 ∧ i0 < j ∧ 0 < i ∧ 0 < j0 → (j * i - i0) / (j * j0) = (i - 1) / j0 subst: [i0, j, i, j0] → [i0, j, i, 1] flags: current, []
