Proof step 1 from proof maxScale-pot10-01 (conclusion)

⊦ i % 10 ≠ 0 ∧ 0 ≤ j → maxScale(i * 10 ^ j) = j

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
0 ≤ j ⊦ maxScale(i * 10 ^ j) = j, i % 10 = 0

Rule argument

Additional information

Used simplifier rules: forward-le-01: ⊦ i ≤ j ∧ 0 ≤ i → 0 ≤ j; (forward) from specification int-abs
