A subscript is a number, figure, or indicator that appears below the normal line of type, typically used in a formula, mathematical expression, or description of a chemical compound. Probably the most famous example of a subscript is the number 2 in the formula for the molecule of water: H2O. Subscripts is also used frequently in mathematics to define starting or final positions; for example, in an equation the following x0 and >O correctly, the 2 should be about 2/3 the size of the H and the O. This is done automatically in many text editing and word processing programs.
- In HTML and Wiki syntax, subscript text is produced by putting it inside the tags

- In TeX's math mode (as used in MediaWiki), subscripts are typeset with the underscore _:
