Calculating Normal Vector of Plane formed by 3 points?

Suppose I have 3 points in 3d space shown in the image. How would I get the normal vector of the plane created by each of the vector3s?

Given some triangle △ABC the normal is the unit vector of (B-A)×(C-A), i.e. ((B-A):Cross(C-A)).Unit. The direction of the normal depends on the order of the vertices.
