Proof step 2 from proof modlep (previous step)

j0 < j, 0 ≤ j0, j * i ≤ j * i0 + j0 ⊦ i ≤ i0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

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

Rule argument

Additional information

Used simplifier rules: forward-lels: ⊦ i ≤ j ∧ j < j0 → i < j0; (forward) from specification int-abs% ⊦ i ≤ j ↔ ¬ j < i; (ss)
