Proof step 14 from proof neg-any-def (previous step)

∀ i0, j. i→n(i0) < i→n(i) → true → mkDecimal(~ i0, j) = ~ mkDecimal(i0, j) ⊦ mkDecimal(~ i, j) = mkDecimal(~ i, abs(j)), i = 0, i % 10 = 0, j = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: decimal inst: name: mkDecimal-scale-not-neg seq: ⊦ mkDecimal(i, j) = mkDecimal(i, abs(j)) subst: [j, i] → [j, ~ i] flags: rewrite
