Proof step 2 from proof two-03 (previous step)

m * m0 = 2 ⊦ m = 1, m = 2 ∧ m0 = 1

User applied rule cut formula

And obtained the following new goals

Proof step 3:
m * m0 = 2 ⊦ m = 2, m = 1, m = 2 ∧ m0 = 1

Rule argument

fma: m = 2

Additional information

Used simplifier rules: twoeq: ⊦ 2 = 2 * n ↔ n = 1;%mult-a: ⊦ m0 * m * n = (m0 * m) * n;%mult-c: ⊦ m * n = n * m; Used formulas: m = 2
