 :A symbol centered underneath another larger symbol is normally reserved for doing summations or products, where the big symbol is &Sigma; or &Pi;, or some other operation applied to a sequence of numbers. It does not make sense to have a single number on top of a smaller one.

In this case, ''2 choose 2'' is equal to one combination.
-:The usage mentioned in the title text is an operation (e.g. &Sigma; for summation) over a variable, usually indicated by a letter such as i, where the operation is performed over all values of the variable (i.e., you &Sigma; (sum) the argument over all values of i). In the "2" case, the title text says "you 2 the argument over all values of 2" (i.e., the &Sigma; operation has been replaced by the "2" operation and the i variable has been replaced by the "2" variable). 2 is usually not an operation, though the definition of 2 under {{w|Church_encoding#Church_numerals|Church encoding}} is a function that takes in and produces functions. 2 applied to 2 in Church encoding is 4. However, the title text implies that 2 is treated like a variable, which it is not (and it's definitely not a operator and variable at the same time).

 This demonstrates the different ways in which the number 2 can be typeset in various scientific fields.  While these ways of typesetting are used with any number, using the number 2 in this instance provides a clear illustration how adding numbers can significantly alter a feature of a concept (such as the number of electrons in an atom) or perform a mathematical operation on it (such as raising a value to its second power).

 :The number 2 in parentheses that follow a term would normally be the argument to a {{w|Function (mathematics)|function}}.
