\textheight 24cm % 
\hoffset-2cm        % Das sind Formatanweisungen
\voffset-2cm        %

\usepackage[ngerman]{babel}  % Da sind vermutlich u.a. Trennungsregeln im Deutschen enthalten
\usepackage{amssymb}            % Hier sind u.a. die Symbole für "Blackboard-Buchstaben" (z.B. N, Z und Q) enthalten

\textwidth17cm                          % Ist sicher auch eine Formatanweisung

\pagestyle{empty}                      %  Dadurch werden keine Seiten nummeriert. (Können Sie auch wegnehmen)

\parskip2ex                                % Das sieht wieder aus wie eine Formatanweisung (weiß nicht mehr genau, was es war)
\parindent0pt                             % Das bedeutet, glaube ich, dass es keinen Einzug bei einem neuen Absatz gibt
\def\oacc#1{\ifmmode\mathaccent23{#1}\else\accent23{#1}\fi} % keine Ahnung, was das war
