Proof step 3 from proof square-eq-03 (previous step)

m * (m + m0) = n * (n + m0), m < n ⊦ m = n

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: <toplevel> name: square-ls-05 seq: ⊦ m * (m + m0) < n * (n + m0) ↔ m < n subst: [m, m0, n] → [m, m0, n] flags: <rotated> <all paths>
