I want to create a maths workbook using LaTeX. Can you give me some suggestions about which packages to use and how to use them? I'd also like to somehow insert "reference" to each problem with source for problem and to list in the end of the book all sources for each task separately. So when I re-order tasks and move them though sections and chapters, the list of sources still "links" correctly. The same with solutions, since they are going to be on the very back in the book. They will be whole solutions with explanation, not just one number (so they will go one below each other).
I'm relatively new to LaTeX, I know how to use basic commands and I know how to find specifics things I don't know, but this is just too general and "latex workbook" on Google doesn't help much. And I'm sorry but I have no idea how to tag this question. Thanks in advance.
