Proof step 6 from proof negate-01 (
previous step
)
⊦ rational(~ i, 0) = ~ rational(i, 0)
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 7
:
⊦ rational(i, 0) = rational(i, 1)
Proof step 8
:
⊦ rational(~ i, 0) = ~ rational(i, 1)
Rule argument
name: zero-denom rotate: F subst: [i] → [i]
