Proof step 26 from proof divi-same (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 27:
⊦ m ≤ n → dist(m, n) = n - m
Proof step 28:
m * n1 = dist(n0, m * n2 + n) ⊦ m | dist(n, n0), n0 ≤ m * n2 + n
Proof step 32:
m * n1 = m * n2 + n - n0, n0 ≤ m * n2 + n ⊦ m | dist(n, n0)

Rule argument

spec: <toplevel> name: dist-fst seq: ⊦ m ≤ n → dist(m, n) = n - m subst: [n, m] → [m * n2 + n, n0] flags: <all paths>

Additional information

Used terms: m * n2 + n, n0
