Proof step 2 from proof modp (previous step)

m < n, n0 < m0, m0 * n ≤ m0 * m + n0 ⊦

User applied rule structural induction

And obtained the following new goals

Proof step 3:
n0 < m0, m1 +1 < n, m0 * n ≤ m0 * m1 +1 + n0, ∀ n, n0, m0. ¬(m1 < n ∧ n0 < m0 ∧ m0 * n ≤ m0 * m1 + n0) ⊦

Rule argument

term: m

Additional information

Used simplifier rules: mult-base: ⊦ m * 0 = 0;%mult-a: ⊦ m0 * m * n = (m0 * m) * n;%mult-c: ⊦ m * n = n * m;%le-05: ⊦ m < n → (n * n0 ≤ m ↔ n0 = 0);%nat freely generated by 0, +1;;% ⊦ n + 0 = n; (s)%a: ⊦ (m + n0) + n1 = m + n0 + n1; from specification nat-basic%c: ⊦ m + n = n + m; from specification nat-basic% ⊦ 0 < m ↔ m ≠ 0; (s)
