Proof step 1 from proof add-zero-01 (conclusion)

⊦ rational(0, j1) + rational(i0, j0) = rational(i0, j0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ rational(0, j) = rational(0, 1)
Proof step 3:
⊦ rational(0, 1) + rational(i0, j0) = rational(i0, j0)

Rule argument

name: zero-num rotate: F subst: [j] → [j1]
