On the Layout tab of Page Setup, click the button for Line Numbers... and
clear the check box for "Add line numbering." Note, however, that there may
be a reason for them. For example, if the document you were sent was a
journal article for review, the line numbers would be there to facilitate
your reference to specific points in the document.
