## Vector Space

A vector space over is a set of Vectors for which any Vectors , , and and any Scalars , have the following properties:

1. Commutativity:

3. Additive identity: For all ,

4. Existence of additive inverse: For any , there exists a such that

5. Associativity of scalar multiplication:

6. Distributivity of scalar sums:

7. Distributivity of vector sums:

8. Scalar multiplication identity:

An -D vector space of characteristic two has

distinct Subspaces of Dimension .

A Module is abstractly similar to a vector space, but it uses a Ring to define Coefficients instead of the Field used for vector spaces. Modules have Coefficients in much more general algebraic objects.
