-\begin{frame}{Problem 1.1}
-  The aliquot of a number is defined as: the sum of the \emph{proper} divisors of the number. For example:\\
-aliquot(12) = 1 + 2 + 3 + 4 + 6 = 16.\\
-  Write a function that returns the aliquot number of a given number. 
-\end{frame}
-
-\begin{frame}{Problem 1.2}
-  Pair of numbers (a, b) is said to be \alert{amicable} if aliquot number of a is b and aliquot number of b is a.\\
-  Example: \texttt{220, 284}\\
-  Write a program that prints all four digit amicable pairs.
