Proof step 3 from proof even-06 (previous step)

∀ m. m + m ≠ n0 + n0 + 1, m + m = n0 +1 + n0 +1 + 1 ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
m + m = 3 + n0 + n0, ∀ m. m + m ≠ n0 + n0 + 1 ⊦

Rule argument

Additional information

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