Proof step 1 from proof zero-10 (conclusion)

⊦ 0 ≤ i → 0 ≤ i / (n→i(n) + 1)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
i / (n→i(n) + 1) < 0, 0 ≤ i ⊦

Rule argument

Additional information

Used simplifier rules: zero-gels-01: ⊦ i < 0 ∧ 0 ≤ j → i < j; from specification int-abs%forward-le-01: ⊦ i ≤ j ∧ 0 ≤ i → 0 ≤ j; (forward) from specification int-abs%forward-le-02: ⊦ j < i ∧ i ≤ 0 → j < 0; (forward) from specification int-abs%forward-lsle: ⊦ i < j ∧ j ≤ j0 → i < j0; (forward) from specification int-abs%lels-01: ⊦ ¬ i ≤ j ↔ j < i; from specification int-abs
