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

∀ i0, j. i→n(i0) < i→n(i) → true → abs(mkDecimal(i0, j)) = mkDecimal(abs(i0), j) ⊦ mkDecimal(abs(i), abs(j)) = mkDecimal(abs(i), 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, abs(i)] flags: rewrite

Additional information

Used terms: j, abs(i)
