Proof step 2 from proof addarrays-one-01 (previous step)

0 ≤ i ⊦ addarrays(r ', ty, i ', j, st) = addarray(r, mktype_from_dims(ty, countdims(i ', j)), i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ 0 ≤ i → addarrays(r ', ty, i ', j, st) = addarray(r, mktype_from_dims(ty, countdims(i ', j)), i, st)

Rule argument

[crewrite-arg: addarrays-one , F , [st, j, i, ty, r] → [st, j, i, ty, r] ]
