How are footnotes numbered by default in a document?

Footnotes in a document are typically numbered by default in a sequential manner using Arabic numerals, such as 1, 2, 3, and so on. This format helps to clearly indicate the order of references, making it easy for readers to follow along and find the corresponding footnotes at the bottom of the page. Each number corresponds to a specific citation or note that provides additional information or clarification about the text.

Other numbering formats, such as letters (A, B, C) or Roman numerals (I, II, III), are less common for footnotes and might not be utilized for standard document formatting, especially in academic or professional works. The use of Arabic numerals ensures a straightforward and universally understood referencing system.
