Proof step 12 from proof int2bits-lelen-07 (previous step)

0 ≤ j, 2 ^ n→i(# int2bits(~ j)) + j < 0 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 13:
¬ i < 0, ¬ j < 0 ⊦ ¬ i + j < 0

Rule argument

seq: ¬ i < 0, ¬ j < 0 ⊦ ¬ i + j < 0 subst: [j, i] → [j, 2 ^ n→i(# int2bits(~ j))] rotate: F spec: int-basic2 inst: name: pls-01

Additional information

Used simplifier rules: ⊦ ¬ 2 ^ i < 0;% ⊦ i ≤ j → ¬ j < i; Used terms: j, 2 ^ n→i(# int2bits(~ j))
