| i < j, i % j + 1 < j, j + i % j < 0, 0 < j, i % j < ~1, i % j < 0, i < 0, i + 1 < j ⊦ |
⊦ 0 < j ∧ i < 0 → (i0 = i / j ∧ j0 = i % j ↔ i = i0 * j + j0 ∧ j0 ≤ 0 ∧ abs(j0) < j)
Used simplifier rules: ⊦ i < 0 → abs(i) = ~ i; (s)% ⊦ ~ i < j ↔ 0 < j + i; (s)% ⊦ i < j → ¬ j < i; (s) Used terms: i, j, i0, j0
