Proof step 10 from proof num-neg-01 (previous step)

i ≠ 0 ∧ 0 < 1 ⊦ i / gcd(i, 1) + rational(~ i, 1).num = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
⊦ i = 0, rational(~ i, 1).num + i = 0

Rule argument

Additional information

Used simplifier rules: ⊦ i / 1 = i;% ⊦ gcd(i, 1) = 1;
