Theorem: Smt.Reconstruct.Int.combine_signs₂ (Smt/Reconstruct/Int/Lemmas.lean)

State before:
a b c d : Int
⊢ a > 0 → b < 0 → b * a < 0
Tactic:
intros h₁ h₂
State after:
a b c d : Int
h₁ : a > 0
h₂ : b < 0
⊢ b * a < 0

State before:
a b c d : Int
h₁ : a > 0
h₂ : b < 0
⊢ b * a < 0
Tactic:
have h := Int.mul_lt_mul_of_pos_right h₂ h₁
State after:
a b c d : Int
h₁ : a > 0
h₂ : b < 0
h : b * a < 0 * a
⊢ b * a < 0

State before:
a b c d : Int
h₁ : a > 0
h₂ : b < 0
h : b * a < 0 * a
⊢ b * a < 0
Tactic:
simp at h
State after:
a b c d : Int
h₁ : a > 0
h₂ : b < 0
h : b * a < 0
⊢ b * a < 0

State before:
a b c d : Int
h₁ : a > 0
h₂ : b < 0
h : b * a < 0
⊢ b * a < 0
Tactic:
