Proof step 16 from proof div2-nls-02 (previous step)

i + j = i0 * 2 + j0, j0 < 2, i0 < i, i ≤ j, 0 ≤ j0, 0 ≤ i0, 0 ≤ i + j, i0 < j, 0 < i, 0 < j ⊦

User applied rule cut formula

And obtained the following new goals

Proof step 17:
j0 = 1, i + j = i0 * 2 + j0, j0 < 2, i0 < i, i ≤ j, 0 ≤ j0, 0 ≤ i0, 0 ≤ i + j, i0 < j, 0 < i, 0 < j ⊦
Proof step 19:
i + j = i0 * 2 + j0, j0 < 2, i0 < i, i ≤ j, 0 ≤ j0, 0 ≤ i0, 0 ≤ i + j, i0 < j, 0 < i, 0 < j ⊦ j0 = 1

Rule argument

fma: j0 = 1

Additional information

Used formulas: j0 = 1
