Proof step 2 from proof mone-01 (
previous step
)
0 = i + 1, i < 0 ⊦ i = ~1
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 3
:
⊦ i = ~1 ↔ i +1 = 0
Rule argument
spec: int-basic1 inst: name: mone seq: ⊦ i = ~1 ↔ i +1 = 0 subst: [i] → [i] flags: rewrite
Additional information
Used simplifier rules: succ-01: ⊦ i +1 = i + 1; Used terms: i
