((m0 * n + n0) + n) / n = (m0 * n + n0) / n + 1, ∀ n0, n. (n0 + m0 * n) / n = n0 / n + m0 ∨ n = 0 ⊦ (n0 + n * m0) / n = n0 / n + m0, n = 0

Additional information

Used simplifier rules: add: n ≠ 0 ⊦ (n0 + n) / n = n0 / n + 1;% ⊦ m + n = m + n0 ↔ n = n0; (s)%c: ⊦ m + n = n + m; from specification nat-basic%a: ⊦ (m + n0) + n1 = m + n0 + n1; from specification nat-basic
