Proof step 13 from proof div-minus-onediff-01 (previous step)

j0 = i0 + 1, 0 < j, j0 < 0 ⊦ j = 0, (i0 * j + 1) / j = j0, 1 % j = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 14:
0 < j, i0 < ~1 ⊦ j = 0, (i0 * j + 1) / j = i0 + 1, 1 % j = 0

Rule argument
