Proof step 2 from proof is-aligned-le-eq-zero (previous step)

is-aligned(n, m) ⊦ m ≤ n ↔ n ≠ 0, m = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
⊦ is-aligned(n, m) ↔ n % m = 0

Rule argument

Additional information

Used simplifier rules: is-aligned-def: ⊦ is-aligned(n, m) ↔ n % m = 0;% ⊦ m < n → m % n = m; (s)% ⊦ m ≤ n ↔ ¬ n < m; (ss)% ⊦ m ≤ 0 ↔ m = 0; (s)
