| i % j < 0, 0 < j, i < 0, i < j, j + i % j ≤ 0 ⊦ i % j = 0 |
⊦ 0 < j ∧ i < 0 → (i0 = i / j ∧ j0 = i % j ↔ i = i0 * j + j0 ∧ j0 ≤ 0 ∧ abs(j0) < j)
Used simplifier rules: ⊦ i ≠ j → (i ≤ j ↔ i < j); (s)% ⊦ i < 0 ∧ 0 ≤ j → i < j; (s)% ⊦ i < 0 → abs(i) = ~ i; (s)% ⊦ ~ i < j ↔ 0 < j + i; (s)% ⊦ i ≤ j → ¬ j < i; (s) Used terms: i, j, i1, j1
