Proof step 1 from proof abs-nodes-prefix-elim (conclusion)

⊦ abs-nodes(buf0, x0, lax0, false) → (abs-nodes(buf0 + buf1, x1, lax1, boolvar1) ↔ (∃ x2, lax2. x1 = x0 + x2 ∧ lax1 = lax0 + lax2 ∧ abs-nodes(buf1, # buf0, x2, lax2, boolvar1)))

System applied rule normalize

And obtained the following new goals

Proof step 2:
abs-nodes(buf0, x0, lax0, false) ⊦ abs-nodes(buf0 + buf1, x1, lax1, boolvar1) ↔ (∃ x2, lax2. x1 = x0 + x2 ∧ lax1 = lax0 + lax2 ∧ abs-nodes(buf1, # buf0, x2, lax2, boolvar1))
