Proof step 3 from proof eq-01 (previous step)

m0 +1 + n = m0 +1 + n0, ∀ n, n0. m0 + n = m0 + n0 → n = n0 ⊦ n = n0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
m0 + n = m0 + n0, ∀ n, n0. m0 + n = m0 + n0 → n = n0 ⊦ n = n0

Rule argument

Additional information

Used simplifier rules: rec: ⊦ m +1 + n = (m + n)+1;%a: ⊦ (m + n0) + n1 = m + n0 + n1;%c: ⊦ m + n = n + m;%inj: ⊦ n +1 = n0 +1 ↔ n = n0;
