Header, Footer, and Page Number

We were told to do a business letter that should contain header, footer and page number. Header is located on top of the paper. To make one, double click on the top portion of the paper in MS Word program. Footer, basing it on its name is like a foot meaning located way below the page to be worked with.To make a footer, double click at the bottom of the paper being worked with in MS Word program also. We do also page number for easier navigation of page being worked with.
