Proof step 5 from proof div-div (previous step)

0 ≤ abs(i) ∧ 0 < abs(j) ∧ 0 < abs(j0) → (abs(i) / abs(j)) / abs(j0) = abs(i) / (abs(j) * abs(j0)) ⊦ (i / j) / j0 = i / (j * j0), j = 0, j0 = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
(abs(i) / abs(j)) / abs(j0) = abs(i) / (abs(j) * abs(j0)) ⊦ (i / j) / j0 = i / (j * j0), j = 0, j0 = 0

Rule argument

Additional information

Used simplifier rules: ⊦ 0 < abs(i) ↔ i ≠ 0; (s)% ⊦ 0 ≤ abs(i); (s)
