In this section we will examine the concept of subspaces introduced earlier in terms of Rn. Here, we will discuss these concepts in terms of abstract vector spaces.

It offers examples of valid and invalid subspaces, discusses conditions specific to R2, and explains spanning sets of subspaces, particularly the column and null spaces of matrices.
