Proof step 36 from proof modby6-help (previous step)

⊦ i + (i * i) * 3 + i * i * 2 * i = i * ((i + 1) * 2 * i + i + 1)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-mult name: dist-lsplit seq: ⊦ (i + i0) * j = i * j + i0 * j subst: [j, i0, i] → [2 * i, 1, i] flags: <all paths>
