Proof step 7 from proof pot2-le-pred (previous step)

2 ^ i < 1 / 2 ^ abs(i - 1), i - 1 < 0, i ≤ 0 ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
2 ^ i < 1 / 2 ^ abs(i - 1), i ≤ 0 ⊦

Rule argument

Additional information

Used simplifier rules: ⊦ i < 1 ↔ i ≤ 0; (s)% ⊦ i - j < i0 ↔ i < j + i0; (s)
