LaTeX style guide

Here are some guidelines for when writing LaTeX

Writing equations

All equations should be written around the \begin{align*} environment, as follows:

\begin{align*}
	x = \frac {-b \pm \sqrt{b^2 -4ac}} {2a}
\end{align*}

Concatenated enumerates

\begin{enumerate}[label=(\alph*)]
	\item For the given points $A$ to $G$, determine in which instants:
		\begin{enumerate}[label=(\roman*)]
			\item The car is at rest
			\item The car is neither accelerating nor decelerating
			\item The car changes direction
		\end{enumerate} \marginpar{[6]}
\end{enumerate}
