Real results from the same practice PDF
Starting at 5 adds 5, 6 and 7 to the three original pages. Compare bottom center, bottom right and top center below. Existing page numbers remain, so choose space without a header or footer. To exclude a cover, split the document first, number the body and merge the files again.
