Proof step 5 from proof div-eq-zero-01 (previous step)

⊦ i / j = 0 ↔ abs(i) < abs(j), 0 = j, 0 < i ∧ 0 < j

User applied rule cut formula

And obtained the following new goals

Proof step 6:
i < 0 ⊦ i / j = 0 ↔ abs(i) < abs(j), 0 = j, 0 < i ∧ 0 < j
Proof step 26:
⊦ i < 0, i / j = 0 ↔ abs(i) < abs(j), 0 = j, 0 < i ∧ 0 < j

Rule argument

fma: i < 0
