Proof step 14 from proof mod-zero-one (previous step)

i0 % j + i % j < 2 * j, 0 < j, 1 < (i % j + i0 % j) / j, 0 < (i % j + i0 % j) / j, 0 ≤ i, 0 ≤ i0 ⊦ (i % j + i0 % j) / j = 1, (i % j + i0 % j) / j < (2 * j) / j

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: <toplevel> name: num-ls seq: ⊦ 0 < j ∧ 0 ≤ i → (i / (* j) < j0 ↔ i < j * j0) subst: [j0, j, i] → [(2 * j) / j, j, i % j + i0 % j] flags: <all paths>
