Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

i can understand why hard links can change that number,but still confused with the number of a directory.
Do you mean the "Total <number>" part of the command output? if yes, then check this from the GNU page on the ls command :
For each directory that is listed, preface the files with a line ‘total blocks’, where blocks is the total disk allocation for all files in that directory. The block size currently defaults to 1024 bytes, but this can be overridden (see Block size). The blocks computed counts each hard link separately; this is arguably a deficiency.
The formula (2 + number_of_subdirs) is correct for the root directory too. It's just that in the root directory, one of those "2" links is different. In a non-root directory, there is one link from the parent directory plus the directory's own "." link. In the root directory, there is no parent directory, but both "." and ".." point to the root directory, so there are still 2 links.
BTW, when you want to post something with spacing preserved, just wrap it in [CODE] ... [/CODE] tags. The "#" icon in the toolbar will do that for you.
