Proof step 4 from proof nls-mult-div (previous step)

i = 0, 0 < (i * i1) / j, 0 < j, i < (i * i1) / j, i1 < j, 0 ≤ i ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
i1 < j, 0 < j, 0 < 0 / j ⊦

Rule argument

Additional information

Used simplifier rules: commutativity: ⊦ i * j = j * i; from specification int-mult%associativity: ⊦ i * j * j0 = (i * j) * j0; from specification int-mult% ⊦ i * 0 = 0; (s)
