Definition. We define struct_b_b_e_e_semiring to be λR ⇒ struct_b_b_e_e R ∧ unpack_b_b_e_e_o R (λR plus mult zero one ⇒ (∀x y z ∈ R, plus (plus x y) z = plus x (plus y z)) ∧ (∀x y ∈ R, plus x y = plus y x) ∧ (∀x ∈ R, plus x zero = x) ∧ (∀x y z ∈ R, mult (mult x y) z = mult x (mult y z)) ∧ (∀x ∈ R, mult x one = x ∧ mult one x = x) ∧ (∀x y z ∈ R, mult x (plus y z) = plus (mult x y) (mult x z)) ∧ (∀x y z ∈ R, mult (plus x y) z = plus (mult x z) (mult y z)) ∧ (∀x ∈ R, mult x zero = zero) ∧ (∀x ∈ R, mult zero x = zero)) of type set → prop.
