How are footnotes numbered by default?

By default, footnotes are typically numbered consecutively throughout a document, starting with the number 1 for the first footnote, then 2 for the second, and so on. In most Word processing software, such as Microsoft Word, the numbering is automatically updated if footnotes are added or removed. The numbers are usually displayed as superscripts in the text, corresponding to the detailed footnote text at the bottom of the page.
