An equation is a mathematical statement that two mathematical expressions are equal (indicated by the sign =). Microsoft Equation helps you type fractions, exponents, integrals, and so on in Word documents. In addition, Word allows you to insert an equation from the Gallery, create a new equation, edit, change, or delete a part or the entire equation.

If you use citations in your Word documents, you might need the bibliographic items for each source that you have referenced. Microsoft Word offers a useful tool to create a list of these bibliographic references, also named as Bibliography, References, or Works Cited, as a list of the citations added in the document.

Requirements for book, reports, thesis, and other documents, in addition to page numbers, demand a piece of additional document information located at the top or bottom of each page. To display duplicating information such as a document title, author or responsible person name, date of the last modification, etc., use the Header at the top of every page or the Footer at the bottom of every page.

To fill in the Tables of Contents and Table of Figures according to most requirements, you need to use the formatting settings. Sometimes it is enough just to place the appropriate break signs correctly.

All TOC styles extend the Body style of the document theme, but each TOC style has a specific indent and spacing settings. By default, Word uses the styles defined in the template attached to the document (by default, the template is normal.dotx):
