Proof step 33 from proof equal-minus-one (previous step)

1 / i ^ ~ j = ~1, j < 0 ⊦ i = ~1, i = 0, j = 0, 0 < i ^ ~ j ∧ i ^ ~ j ≤ 1

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 34:
1 / i ^ ~ j = ~1, j < 0, i ^ ~ j ≤ 0 ⊦ i = ~1, i = 0, j = 0

Rule argument

Additional information

Used simplifier rules: forward-le-04: ⊦ j ≤ i ∧ i ≤ 0 → j ≤ 0; (forward) from specification int-abs%j0 ≠ 0, j ≤ j0 ⊦ i ≤ (* j) → i ≤ (* j0); (s)% ⊦ i < j ↔ ¬ j ≤ i; (ss)% ⊦ 1 < j → 1 / j = 0; (s)% ⊦ i ≤ j ↔ ¬ j < i; (ss)
