Proof step 5 from proof square-le-02 (
previous step
)
i * i < abs(i) ⊦ abs(i) ≤ abs(i) * abs(i)
Heuristic simplifier applied rule simplifier
And obtained the following new goals
Proof step 6
:
i * i < abs(i), abs(i) * abs(i) < abs(i) ⊦
Rule argument
Additional information
Used simplifier rules: ⊦ i ≤ j ↔ ¬ j < i; (ss)
