Statement
forall (Scalar : Sort u), forall (zero : Scalar), forall (one : Scalar), forall (add : forall (a : Scalar), forall (b : Scalar), Scalar), forall (neg : forall (a : Scalar), Scalar), forall (sub : forall (a : Scalar), forall (b : Scalar), Scalar), forall (mul : forall (a : Scalar), forall (b : Scalar), Scalar), forall (law : forall (a : Scalar), @Eq.{u} Scalar (add (neg a) a) zero), forall (a : Scalar), @Eq.{u} Scalar (add (neg a) a) zero
Proof term
fun Scalar => fun zero => fun one => fun add => fun neg => fun sub => fun mul => fun law => fun a => law a
