 The first step is induction on the natural number \isa{k}, which leaves
 two subgoals:

 Here \isa{auto} simplifies both subgoals so that they match the introduction
 rules, which then are applied automatically.%

 The first two subgoals are proved by simplification and the final one can be
 proved in the same manner as in \S\ref{sec:rule-induction}
