Proof step 3 from proof cast-law-sub (previous step)

0 < i, 0 < i ⊦ cast(i, cast(i, j) - j0) = cast(i, cast(i, j) - cast(i, j0))

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

name: cast-law-sub-one-01 rotate: F subst: [j0, j, i] → [j0, cast(i, j), i]

Additional information

Used terms: j0, cast(i, j), i
