I recently found a download of many mathematics ebooks/scans which cover various topics such as real and complex algebra, calculus, complex analysis, geometry, number theory, trigonometry, topology and many many more. There are various books of various different levels of difficulty. I think this would help a lot of students and even allow some, such as myself to 'teach themselves' a lot of things, such as when preparing to go to university. As the site at hand has other, more ethically questionable content, I have downloaded the torrents and attached them to this topic as zip files. To begin downloading, simply download the attachment, unzip the file, ensure your bittorent client is running and double click the .torrent file. For a bittorent client i recommend: http://sourceforge.net/projects/azureus/ Hope you find this of some interest. The torrent files which you need to inform the client of how to begin the downloading process are attached.
