\frametitle{Outline}
\label{sec-1}
In this tutorial, we shall look at
\begin{itemize}
\item Using if/else blocks
\item Using if/elif/else blocks
\item Using the Ternary conditional statement
\end{itemize}
\end{frame}

\frametitle{Question 1}
\label{sec-2}
Given a number, num. Write an if else block to print num, as is, if
it is divisible by 10, else print 10 * num.

\frametitle{Summary}
\label{sec-7}
In this tutorial session we learnt
\begin{itemize}
\item What are conditional statements
\item if/else statement
\item if/elif/else statement
\item Ternary conditional statement - \texttt{C if X else Y}
\item and the \texttt{pass} statement
\end{itemize}
