NOTE 1 If *a* is related to *b* by the function *f*, then:

*f*is said to be defined for*a*,*a*is an argument of the function*f*,*b*is a value of the function*f*and is usually denoted by*f*(*a*).

The argument *a* may be an ordered set of more elementary entities.

NOTE 2 If *A* is the set of all arguments of the function *f* and *B* is a set containing all the values, then:

*f*is said to be a mapping of*A*into*B*,*A*is the domain of the function,*B*is the range or codomain of the function.

NOTE 3 The term "operation" is used in common language for elementary functions such as addition, subtraction, multiplication, division.
