Para escribir este ejemplo, primero hay que definir un contador para las
 fórmulas numeradas en romanos.
 Para ello se inserta lo siguiente en el preámbulo LaTeX:
\end_layout

\begin_layout Standard

\series bold

\backslash
newcounter{rom}
\begin_inset Newline newline
\end_inset


\backslash
renewcommand{
\backslash
therom}{
\backslash
roman{rom}}
\end_layout

\begin_layout Standard
\begin_inset Newpage newpage
\end_inset

Para guardar el valor del contador arábigo 
\series bold
equation
\series default
, se añade al preámbulo lo siguiente
\end_layout

\begin_layout Standard

\series bold

\backslash
newcommand{
\backslash
c@org@eq}{}
\begin_inset Newline newline
\end_inset


\backslash
let
\backslash
c@org@eq
\backslash
c@equation
\begin_inset Newline newline
\end_inset


\backslash
newcommand{
\backslash
org@theeq}{}
\begin_inset Newline newline
\end_inset


\backslash
let
\backslash
org@theeq
\backslash
theequation
\end_layout

\begin_layout Standard
Para poder alternar en el documento entre ambos esquemas de numeración,
 se definen los siguientes comandos en el preámbulo:
\end_layout

\begin_layout Standard

\series bold

\backslash
newcommand{
\backslash
setrom}{
\backslash
let
\backslash
c@equation
\backslash
c@rom
\backslash
let
\backslash
theequation
\backslash

\end_layout

\begin_layout Standard

\end_layout

\begin_layout Standard

\series bold

\backslash
newcommand{
\backslash

\backslash
let
\backslash
c@equation
\backslash
c@org@eq
\backslash

\backslash

\backslash

\end_layout

\begin_layout Standard
para la numeración arábiga.
\end_layout

\begin_layout Standard
Cada fórmula será numerada en arábigos por defecto.
 Para cambiar a numeración en romanos, se inserta el comando 
\series bold

\backslash
setrom
\series default
 en modo TeX.
 Con el comando 
\series bold

\backslash
setarab
\series default
 la numeración retorna a números arábigos.
