Theorem: LO.FirstOrder.Arith.Model.Pow2.div_two_mul_two (Arithmetization/ISigmaZero/Exponential/Pow2.lean)

State before:
M : Type u_1
inst✝⁵ : Zero M
inst✝⁴ : One M
inst✝³ : Add M
inst✝² : Mul M
inst✝¹ : LT M
inst✝ : M ⊧ₘ* 𝐈open
p : M
h : Pow2 p
ne : p ≠ 1
⊢ p / 2 * 2 = p
Tactic:
simp [mul_comm, h.two_mul_div_two ne]
