Proof step 12 from proof distributivity (previous step)

j0 ≠ 0 ∧ j1 ≠ 0, 0 < j, 0 < j0, 0 < j1 ⊦ rational(i, j) * rational(i0 * j1 + j0 * i1, j0 * j1) = rational(i, j) * rational(i0, j0) + rational(i, j) * rational(i1, j1)

Proof step 13:
0 < j1, 0 < j0, 0 < j ⊦ j0 = 0, j1 = 0, rational(i, j) * rational(i0 * j1 + j0 * i1, j0 * j1) = rational(i, j) * rational(i0, j0) + rational(i, j) * rational(i1, j1)
