Proof step 10 from proof divide-by-10 (previous step)

0 ≤ i * 52429 ∧ 0 ≤ 19, i ≤ 65536, 0 ≤ i ⊦ (i * 52429) / 2 ^ 19 = i / 10

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
i ≤ 65536, 0 ≤ i ⊦ (i * 52429) / 524288 = i / 10

Rule argument

Additional information

Used simplifier rules: ⊦ i * j = j * i;% ⊦ i * j * j0 = (i * j) * j0;% ⊦ i ≤ 0 ∧ 0 ≤ j → i ≤ j;% ⊦ 0 < i → (0 ≤ i * j ↔ 0 ≤ j);
