Paul Halmos is known as one of the greatest and most enjoyable expositers of mathematics of the twentieth century. I've certainly learnt a lot about writing in general (not just mathematical) from reading his stuff, and his book "Finite Dimensional Vector Spaces" was an aid to me when I was learning Linear Algebra ten years ago. If the linked text is too long, you might enjoy his shorter piece "Mathematics as Creative Art" [0].
