I need to put the page numbering in the document I'm creating, but this document starts from page 20 for example, so I should use a command that would do something like:
\cfoot{Página \thepage+20 de (Número total de Páginas)}
where \ thepage + 20 would have to display the current page + 20, how to proceed?!
To control page numbering, simply set the value of the counter. In LaTeX, you simply use the beginning of the file to set the counter to start at 20:
\setcounter{page}{20}
So the first page will be 20 and the subsequent pages will be counted normally, adding 1 to the counter.
