Proof step 9 from proof sis-sub-2pot (previous step)

~32768 ≤ i0 ∧ i0 ≤ 32767, ~65536 ≤ i0, i0 < 0, ~32769 < i0 ⊦ i0 = s2i(i2s(i0 + 65536))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
~32768 ≤ i0, i0 < 0 ⊦ i0 = s2i(i2s(i0 + 65536))

Rule argument

Additional information

Used simplifier rules: i0 ≠ 0, i0 < i ⊦ (* i) ≤ j → (* i0) < j;%i0 ≠ 0, i0 ≤ i ⊦ (* i) ≤ j → (* i0) ≤ j;% ⊦ i < 0 ∧ 0 ≤ j → i ≤ j;
