Proof step 5 from proof short-neq-01 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ i < 0 ∧ j < 0 → i + j ≠ 0
Proof step 7:
¬(s2i(sho) < 0 ∧ 65536 * i < 0), s2i(sho) + 65536 * i = 0 ⊦ i = 0 ∧ s2i(sho) = 0, ¬ s2i(sho) ≤ 0 ∧ ¬ i ≤ 0

Rule argument

seq: ⊦ i < 0 ∧ j < 0 → i + j ≠ 0 subst: [j, i] → [65536 * i, s2i(sho)] rotate: F spec: int-basic2 inst: name: zero

Used terms: 65536 * i, s2i(sho)
