Proof step 2 from proof modneqp (previous step)

i * i0 + j0 = i1 * j + j1, i < i1, j0 < j, j1 < j, 0 ≤ i, i0 ≤ j, 0 ≤ i0, 0 ≤ j0, 0 ≤ j1 ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
i * i0 + j0 = i1 * j + j1, j1 < j, j0 < j, i < i1, 0 < j, 0 < i1, 0 ≤ j1, 0 ≤ j0, 0 ≤ i0, i0 ≤ j, 0 ≤ i, 0 ≤ j ⊦
