\subsection{Math-Commands}
All these have to be executed in the math environment.
\begin{itemize}
    \item \verb|\R| Prints $\R$. Same goes for \verb|\C| printing $\C$, etc.
    \item \verb|\floor|\{\textit{math}\} Round down symbol, e.g. $\floor{n}$
    \item \verb|\ceil|\{\textit{math}\} Round up symbol, e.g. $\ceil{n}$
    \item \verb|\hastoeq| or \verb|\mbeq| Has to equal symbol (non-standard), $\hastoeq$
    \item \verb|\Leftrightarrowequiv| Equivalence transformation symbol, $\Leftrightarrowequiv$.
    \item \verb|\Rightarrowequiv| Equivalence transformation symbol, $\Rightarrowequiv$.
    \item \verb|\Leftarrowequiv| Equivalence transformation symbol, $\Leftarrowequiv$.
    \item \verb|\defAs| Define as, i.e. $\defAs$
    \item \verb|\defEquiv| Define as, but with a two-sided implication instead of equality, i.e. $\defEquiv$
    \item \verb|\defImplies| Define as, but with one-sided implication, i.e. $\defImplies$
    \item \verb|\divides| Divider or divides symbol, e.g. $a \divides b$
    \item \verb|\lcm| Least common multiple, $\lcm$
    \item \verb|\arcsinh| Inverse of hyperbolic sine, $\arcsinh$
    \item \verb|\arccosh| Inverse of hyperbolic cosine, $\arccosh$
    \item \verb|\arctanh| Inverse of hyperbolic tangent, $\arctanh$
    \item \verb|\limit|\{\textit{math}\}\{\textit{math}\} Shortened limit notation, $\displaystyle \limit{x}{x_0}$
    \item \verb|\limni| Shortened limit notation for $n \rightarrow \infty$, $\displaystyle \limni$
    \item \verb|\liminfni| Shortened limit inferior notation for $n \rightarrow \infty$, $\displaystyle \liminfni$
    \item \verb|\limsupni| Shortened limit superior notation for $n \rightarrow \infty$, $\displaystyle \limsupni$
    \item \verb|\der|\{\textit{math}\} Derivative, $\displaystyle \der{x}$
    \item \verb|\dern|\{\textit{math}\}\{\textit{math}\} Higher derivative, $\displaystyle \dern{x}{2}$
\end{itemize}
