Proof step 4 from proof cast-mult-neg-02 (previous step)

0 < i ⊦ cast(i, ~ j * 2 ^ i + ~ j0) = cast(i, ~ j0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ 0 < i → cast(i, j * 2 ^ i + j0) = cast(i, j0)

Rule argument

name: cast-mult-add rotate: F subst: [j0, j, i] → [~ j0, ~ j, i]

Additional information

Used terms: ~ j0, ~ j, i
