Proof step 3 from proof test-inc-01 (previous step)

⊦ mkDecimal(mkDecimal(99, 2).int + 1, mkDecimal(99, 2).scale) = mkDecimal(1, 0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i
Proof step 5:
¬(99 % 10 = 0 ∧ 2 ≠ 0 ∧ 99 ≠ 0) ⊦ mkDecimal(99 + 1, mkDecimal(99, 2).scale) = mkDecimal(1, 0)

Rule argument

spec: inst: name: intvalue-base seq: ⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i subst: [j, i] → [2, 99] flags: rewrite, current
