\section*{Writing math on the web can be difficult -- not on
Authorea!}

{\label{974700}}

Writing equations online can be
\href{https://www.authorea.com/users/5713/articles/75598-mathml-on-the-web-please/_show_article}{very
painful}. While there are many options out there for writing simple math
equations, none of them provides as many options as Authorea.

\par\null

\section*{How Authorea helps you write
math}

{\label{603886}}

In \href{http://www.authorea.com}{Authorea}{, you have a few different
choices for writing math. You can use the built-in~}\textbf{Equation
Editor}{~(}{\ref{940296}}{), or the
built-in~}\textbf{LaTeX Editor}{~(}{\ref{896173}}{).
The }Equation Editor{~has two ways to write equations: using the Live
Editor and using the TeX source.}

\par\null

{These options are covered in detail below.}

\par\null

\subsection*{Equation Editor}

{\label{940296}}\par\null

The simplest equation writing tool in Authorea is activated via the
\texttt{Insert\ Equation} button in the toolbar.\selectlanguage{english}

\end{center}
\end{figure}

\par\null\par\null\par\null\par\null

\subsection*{TeX Source}

{\label{663833}}

An alternative equation writing technique is to use the
\texttt{TeX\ Source} option within the \texttt{Insert\ Equation} module.\selectlanguage{english}
\begin{figure}[h!]

\caption{{Write an equation using the TeX Source tab within Insert Equation
{\label{533404}}%
}}
\end{center}
\end{figure}

\par\null

\subsection*{LaTeX Editor}

{\label{896173}}

A third way to write an equation is to use the LaTeX editor itself --
via Insert LaTeX.

\section*{Other options for writing an
equation}

{\label{581985}}

Some other ways to write equations are:

\begin{itemize}
\tightlist
\item
  \href{http://mathquill.com/}{Mathquill}~- a great tool for forming
  equations quickly
\item
  \href{http://www.hostmath.com/}{HostMath} - ~useful way to create
  embedded equations using a variety of sources
\item
  \href{http://math.typeit.org/}{TypeIt}~- a simple and multi-lingual
  tool for creating equations
