Changing the formatting of your document is very easy.
In this example, the mathematical equations are quite simple. There are different ways of writing a bibliography using LaTeX.
But LaTeX really shines when displaying more complex mathematical equations, for example using matrices. LaTeX is best used for large documents or documents with complex layouts or for special needs such as displaying mathematical equations and algorithms.
That's all you need to know about the syntax now. I prefer the LaTeX font.
Personally, I prefer the default LaTeX font. The first problem is that there is a somewhat steep learning curve. The body text of paragraphs is simply plain text. Actually, although, there is a steep learning curve, I think that it is an excellent investment to learn to use LaTeX for researchers.
