Proof step 4 from proof short-neq-02 (previous step)

¬(0 < us2i(sho) ∧ 0 < 65536 * i), us2i(sho) + 65536 * i = 0 ⊦ i = 0 ∧ s2i(sho) = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
us2i(sho) + 65536 * i = 0 ⊦ i = 0 ∧ s2i(sho) = 0, ¬ us2i(sho) ≤ 0 ∧ ¬ i ≤ 0

Rule argument

Additional information

Used simplifier rules: ⊦ i * j = j * i;% ⊦ i * j * j0 = (i * j) * j0;% ⊦ 0 < i → (0 < i * j ↔ 0 < j);% ⊦ ¬ i < j ↔ j ≤ i;% ⊦ i + j = j + i;% ⊦ i + j + i0 = (i + j) + i0;
