• If a vector space $V$ has a basis with $n$ elements, then $n$ is called dimension of $V$.
• If $W$ is a subspace of $V$, then dim(W) = dim(V).
• The span of column of a matrix $A$ is called column space of $A$.
• The span of rows of a matrix $A$ is called row space of $A$.
• If $T:V\to W$ is linear transformation, then $K(T)$, kernel of $T$, is subspace of $V$.
• If $T:V\to W$ is linear transformation, then $R(T)$, range of $T$, is subspace of $W$.
