+\begin{frame}{Preamble}
+  \begin{itemize}
+    \item Include packages with \texttt{\bs usepackage}
+    \item Define properties of the document (\texttt{\bs documentclass},
+          \texttt{\bs author}, ...)
+    \item Define new commands and environments
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Text formatting}

+  Some technicalities:
+  \begin{itemize}
+    \item Blocks are delimited by \{ and \}
+    \item \texttt{\bs textbf\{...\}} etc. are commands with one argument
+    \item \texttt{\bs emph\{...\}} is context-aware (when in doubt use this)
+    \item \texttt{\bs Large} etc. change the text until the end of the block

+
+  \vspace{1.5cm}
+  One can write math inline, like \(\sum_i\frac{i}{2}\) or in displaystyle:
+  \[\sum_i\frac{i}{2}\]
+\end{frame}
+
+\begin{frame}{Math mode}
+  \begin{center}
+    For formulas spanning multiple lines you can use:
+
+    \vspace{0.5cm}
+    \texttt{\color{red}\bs begin\{align\} (...) \bs end \{align\}}
+    \begin{align}
+      e^x =& \sum_{n=0}^{\infty} \frac{x^n}{n!} \\

+
+\begin{frame}{Math mode}
+  \begin{itemize}
+    \item Some people use \texttt{\$2+2=4\$} instead of \texttt{\bs(2+2=4\bs)}
+    \item Some \textbf{evil} people use \texttt{\$\$2+2=4\$\$} instead of
+          \texttt{\bs[2+2=4\bs]} (don't try this at home!)
+    \item For \texttt{align} use \texttt{\bs nonumber} to remove one number
+          and \texttt{\&} to align.
+    \item For example I always use \texttt{\$2+2=4\$} and the \texttt{align*}
+          environment.
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Math mode}
+  \begin{itemize}
+    \item Simple symbols: letters, numbers, $+,-,=,<,>$...

+          \end{tabular}
+          \vspace{0.6cm}

+            \texttt{x \bs not \bs in A} \qquad\to&\qquad x\not\in A\\

+\end{frame}

+\begin{frame}{Math mode}
+  \begin{itemize}

+          \texttt{\bs frac}).
+          
+          Anything can be an argument:

+            \frac{1}{\sum_{n} \sqrt n}
+          \end{align*}
+    \item A few commands take \textbf{options}:
+          \texttt{\bs sqrt[3]\{x\}} $\to\,\sqrt[3]{x}$
+    %\item Most of these commands work only in Math mode
+  \end{itemize}
+\end{frame}
+
+
+\begin{frame}{Math mode}
+  \begin{itemize}
+    \item Every symbol can have a \textbf{subscript} and a \textbf{superscript}

+            \texttt{\bs int\_\{\bs phi (y)\}\^{}\{2\^{}\{n\_1\}\}}
+            \qquad \to \qquad \int_{\phi(y)}^{2^{n_1}}

+  \end{itemize}
+\end{frame}
+
+
+\begin{frame}{Math mode}
+  \begin{itemize}
+    \item Adjust parentheses size with \texttt{\bs left(} and

+    \item Insert text with \texttt{\bs text} and
+          spaces with \texttt{\bs ,} and \texttt{\bs quad}:
+          \[\text{this symbol}\quad \sum_{n=0}^\infty \frac{x^n}{n!} \quad
+            \text{is in math mode}, this is not text\]
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Math mode}
+  
+  \begin{itemize}

+            \mathcal{A} \qquad \mathbb R \qquad \mathfrak p
+          \end{align*}

+          \begin{align*}
+            \operatorname{oper}(x)
+          \end{align*}
+    \item Pro-tip: write \texttt{\bs newcommand\{\bs R\}\{\bs mathbb R\}} and
