\section{Inverses} Try finding $1 \div 32$ using your slide rule. \\ The procedure we learned before doesn't work! \medskip This is why we have the CI scale, or the ``C Inverse'' scale. \problem{} Figure out how the CI scale works and compute the following: \begin{enumerate}[itemsep=1mm] \item $\frac{1}{7}$ \item $\frac{1}{120}$ \item $\frac{1}{\pi}$ \end{enumerate} \vfill \pagebreak
