Proof step 7 from proof short-law-mult-one (previous step)

⊦ cast(16, j * j0) = cast(16, cast(16, j) * j0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 8:
0 < i ⊦ cast(i, j * j0) = cast(i, cast(i, j) * j0)

Rule argument

seq: 0 < i ⊦ cast(i, j * j0) = cast(i, cast(i, j) * j0) subst: [j0, j, i] → [j0, j, 16] rotate: F spec: intops inst: name: cast-law-mult-one

Additional information

Used simplifier rules: ⊦ i * j = j * i; Used terms: j0, j, 16
