TITLE: Tips for writing math solutions for others
QUESTION [5 upvotes]: I am working a bit on a collection of Linear Algebra examples, 
as well as some examples on induction. This is what is taught freshman year at our university.
I intend to release this to the public, either by selling printed copies or releasing it online. 
Since I do not have experience using such material myself, there are some questions I would like some opinions on:

How much theory should I include? Is references to course litterature enough?
Is there a format preference? Small text, so that the collection is more enviromental-friendly, or with big marginals for notes?
Best way to deal with misprints?
Should induction and Linear algeba be separate pieces? 

Please share your experience if you have done something similar.
EDIT:
An answer I seek is something along the lines of:
"I am a "something" stident, and I prefer "something", and would like to see more of "something".

REPLY [11 votes]: I am an undergrad student, and I just finished taking Application of Linear Algebra. Here is what I want from a linear algebra text:
EXAMPLES WHICH ACTUALLY DEMONSTRATE THE POINT.
An example of what I don't ever want to see: the first example in my textbook was to show how to do matrix multiplication. Simple, right? No. They used a square symmetric matrix multiplied by itself to demonstrate this, and didn't walk through the individual steps. It just gave some matrix A and said look! A.A = B. See? And of course we didn't.
So please! Check that your examples can only be understood one way, and that this way is the way you intend.
