Proof step 12 from proof test-divides-02 (previous step)

⊦ mkDecimal(2 * mkDecimal(25, 1).int, mkDecimal(25, 1).scale) = mkDecimal(5, 0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 13:
⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i
Proof step 14:
¬(25 % 10 = 0 ∧ 1 ≠ 0 ∧ 25 ≠ 0) ⊦ mkDecimal(2 * 25, mkDecimal(25, 1).scale) = mkDecimal(5, 0)

Rule argument

spec: decimal inst: name: intvalue-base seq: ⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i subst: [j, i] → [1, 25] flags: rewrite
