Remember: We are using MathJax for mathematical expressions. Text formatting commands of TeX/LaTeX are not supported in MathJax.
Mathematical expressions can be inserted within HTML text of all content types (e.g., page, book page, blog, forum) edited using the available online WYSIWYG HTML editor. The mathematical expressions must be typed using the syntax of TeX/LaTeX.
The easiest way to start is to author a page with some LaTeX code for mathematical expressions given here (based on the code snippets from an online cookbook).
[For a more comprehensive documentation of the TeX commands supported in MathJax, see this document.]
To put mathematical expressions in a line (inline mode), or equations (paragraph mode), we can use single dollar character (\$) or double dollar characters (\$\$) respectively as delimiters to surround the mathematical expression within the HTML editor available for almost all content types (e.g., page, book page, blog, forum).
Of course, the mathematical expressions must be typed using a special syntax (TeX/LaTeX).
Easiest way to start is to author a page with some LaTeX code for mathematical expressions given below (code snippets from an online cookbook). If you copy-paste code snippet from the examples below, do not forget to select and change the format (first drop-down in toolbar) of the pasted text from Preformatted to Paragraph.

In-line maths elements can be set with a different style: \(f(x) = \displaystyle \frac{1}{1+x}\).
The same is true the other way around: \begin{eqnarray*}
f(x) = \sum_{i=0}^{n} \frac{a_i}{1+x} \\
\textstyle f(x) = \textstyle \sum_{i=0}^{n} \frac{a_i}{1+x} \\
\scriptstyle f(x) = \scriptstyle \sum_{i=0}^{n} \frac{a_i}{1+x} \\
\scriptscriptstyle f(x) = \scriptscriptstyle \sum_{i=0}^{n} \frac{a_i}{1+x}
\end{eqnarray*}
