Proof step 2 from proof short-neq-01 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ 0 < i ∧ 0 < j → i + j ≠ 0
Proof step 4:
¬(0 < s2i(sho) ∧ 0 < 65536 * i), s2i(sho) + 65536 * i = 0 ⊦ i = 0 ∧ s2i(sho) = 0

Rule argument

seq: ⊦ 0 < i ∧ 0 < j → i + j ≠ 0 subst: [j, i] → [65536 * i, s2i(sho)] rotate: F spec: int-basic2 inst: name: not-zero-pos

Additional information

Used terms: 65536 * i, s2i(sho)
