Proof step 8 from proof short-neq-01 (previous step)

s2i(sho) + 65536 * i = 0 ⊦ i = 0 ∧ s2i(sho) = 0, ¬ s2i(sho) ≤ 0 ∧ ¬ i ≤ 0, ¬ 0 ≤ s2i(sho) ∧ ¬ 0 ≤ i

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ i + j = 0 ↔ i = ~ j
Proof step 10:
s2i(sho) = ~(65536 * i) ⊦ i = 0 ∧ s2i(sho) = 0, ¬ s2i(sho) ≤ 0 ∧ ¬ i ≤ 0, ¬ 0 ≤ s2i(sho) ∧ ¬ 0 ≤ i

Rule argument

seq: ⊦ i + j = 0 ↔ i = ~ j subst: [j, i] → [65536 * i, s2i(sho)] rotate: F spec: int-abs inst: name: rew-eqzero
