Proof step 34 from proof divi-same (previous step)

m * n2 + n = m * n1 + n0 ⊦ m | dist(n, n0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 35:
⊦ m ≤ n → dist(m, n) = n - m
Proof step 36:
m * n2 + n = m * n1 + n0 ⊦ m | dist(n, n0), n ≤ n0
Proof step 50:
m * n2 + n = m * n1 + n0, n ≤ n0 ⊦ m | n0 - n

Rule argument

spec: <toplevel> name: dist-fst seq: ⊦ m ≤ n → dist(m, n) = n - m subst: [n, m] → [n0, n] flags: <all paths>
