Proof step 14 from proof short-law-compl (previous step)

⊦ i2s(cast(16, ~ cast(16, cast(16, i) + 1))) = i2s(cast(16, ~(cast(16, i) + 1)))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 15:
0 < i ⊦ cast(i, ~ j) = cast(i, ~ cast(i, j))

Rule argument

seq: 0 < i ⊦ cast(i, ~ j) = cast(i, ~ cast(i, j)) subst: [j, i] → [cast(16, i) + 1, 16] rotate: F spec: intops inst: name: cast-law-neg

Additional information

Used simplifier rules: ⊦ i + j = j + i; Used terms: cast(16, i) + 1, 16
