This manual includes important features as follows: -Many examples of widely used mathematical expressions; -Completing a document that describes the creation of articles, reports, and overhead projector slides; Tips to help you show the error; -Details about how to set up a bibliography and index; -Information about LATEX resources available on the Internet. LATEX typesetting system has become very popular and widely used throughout the sciences. As a student, you may need to set the reports and theses in LATEX (especially if you are a graduate student in mathematics or computer science discipline). Or you may be someone who had planned to "eventually" get around to learn LATEX, but you are still using the old system and methods of typesetting. Old and new versions are very similar and it is clear that the version of LaTeX 2e will soon dominate.
