I have recommended that you learn Latex for writing your mathematical papers. Latex is a kind of typesetting language, aimed at producing nice looking documents, especially documents with mathematical symbols. Here is the general template for an article written in Latex:
\documentclass{article}
\title{Your title here}
\author{Your name here}
\begin{document}
\maketitle
\section{Introduction}
here comes your text, probably with more sections, etc.
\end{document}
All those lines are necessary, except the "section" one -- no one forces you to divide your article into sections. The best part comes when you need special symbols, mathematical equations, etc. There is a mode you can switch into called "math mode." In math mode you can produce Greek letters, subscripts and superscripts, fractions with a horizontal bar, etc. These can be inline -- open math mode with the dollar sign $ and close it with another dollar sign $, like this: $x^2+y^2=\alpha$. Or it can be in an equation area centered on the page and set off from surrounding text. To do this, use\begin{equation}
\alpha + \beta_3=\sqrt{x+y^2}-\frac{2+x}{1+y}
\end{equation}
There is a very nice "environment" for doing this on all the Math Department machines called WinEdt. After preparing a document in the form of the template, and saving it, do three things: (1) Go to the Project menu item, and choose "Set Main File" (you only have to do this at the beginning, so that your file is the one to process) (2) push the "Latex" button at the top of the screen, and (3) (assuming there are no errors) push the "DVI" button to see the typeset version. You can also print from there.
The first time you try this, you will undoubtedly see many errors, but it is worth learning to do -- eventually it becomes very easy, and the benefit is great. More Latex constructions
