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

⊦ i / (j0 * 2) = (i / 2) / j0, j0 = 0

User applied rule cut formula

And obtained the following new goals

Proof step 6:
i % 2 = 0 ⊦ i / (j0 * 2) = (i / 2) / j0, j0 = 0
Proof step 8:
⊦ i % 2 = 0, i / (j0 * 2) = (i / 2) / j0, j0 = 0

Rule argument

fma: i % 2 = 0

Additional information

Used formulas: i % 2 = 0
