Consider the set of all linear transformations from $V$ to $W$ to be a vector space over $F$. What is the dimension of vector space? Demonstrate an explicit basis. You may use usual matrix arithmetic without proof.

I've been working on this question for a while and have made no progress. How should I proceed? Thanks for all of your help.

@Neal Sorry about that. I edited the question. –  Juan Gomez Oct 29 '12 at 1:01
    
What do you know about the representation of linear maps as matrices? –  wj32 Oct 29 '12 at 1:08
    
@wj32 Not much at all to be honest. –  Juan Gomez Oct 29 '12 at 1:09
    
What do you get if multiply a matrix $A$ by $(1,0,0,..)^T$ from the right? –  Berci Oct 29 '12 at 1:12

I am guessing you mean finite dimensional vector spaces. Let $\dim(V)=n$ and $\dim(W)=m$.

Hint: after you fix a basis for $V$ and $W$, each linear transformation is expressible as an $n\times m$ matrix acting on the right of row vectors of length $n$.
