Which of the following is an advantage of inserting a page number field in your document rather than inserting each page number
Artyom0805 [142]

The advantage of inserting the page number field is that the page number field could show the current page number.

The following information should be relevant with respect to the page number:

  • The page number field & the actual page number should be formatted.
  • The page number field & the actual page number both could be inserted into the header or footer.
  • The page number field & the actual page number could be easily inserted into the document.

Therefore we can conclude that the advantage of inserting the page number field is that the page number field could show the current page number.
