But why is it important?

Read about its uses in a couple of those web sites.

A subscript is a small character or number written just below and to the right of a regular-sized character or number. It is commonly used in mathematical expressions, chemical equations, and programming languages to denote specific information or types of data.

In mathematics, subscripts are used to represent indices or variables that are associated with a particular element or term in a sequence, matrix, or equation. For example, in the equation Xn, the subscript "n" represents the position of the term in the sequence or series.

In chemistry, subscripts are used to indicate the number of atoms in a chemical formula. For instance, H2O represents two hydrogen (H) atoms and one oxygen (O) atom.

In programming languages, subscripts are used to access specific elements or variables in arrays or lists. By specifying an index enclosed in square brackets, we can retrieve or modify a particular element's value. For example, in the expression myList[2], the subscript "2" refers to the third element in the list.

Subscripts are important because they provide precise and concise notations, allowing us to convey specific information or relationships. They help distinguish between different elements or terms within a context, making mathematical expressions, chemical formulas, and programming code more understandable and unambiguous. By adhering to the appropriate use of subscripts, we can effectively communicate complex ideas and formulas.
