Field (Mathematics)

The prototypical example of a field is Q, the field of rational numbers. Other important examples include the field of real numbers R, the field of complex numbers C and, for any prime number p, the finite field of integers modulo p, denoted Z/pZ, Fp or GF(p). For any field K, the set K(X) of rational functions with coefficients in K is ... a field.

At the present time in mathematics education, such discussion is particularly critical to the ongoing growth and strength of the field. Mathematics education research has evolved significantly in the last 20 years. The most sweeping change has been the acceptance and subsequent predominance of qualitative research methodologies. With this change has come a plethora of new and adapted methodologies. On one hand, this is a sign of the field's vitality. On the other hand, the rapid changes and diversity in how research is conducted have posed major challenges with respect to standards for research quality (Lesh, Lovitts, & Kelly, 2000).

Mathematics is a valuable tool in the Actuarial field. What an actuary does is create and maintain valuable statistics that help organizations predict the future. An actuary has an abundance of mathematical skills, enjoys problem-solving, and is usually a curious person who is interested in doing research. Besides these qualities that an actuary normally possesses, one must be able keep up on current trends and business issues, as well as know the latest information in the social sciences, law, and economics. This knowledge enables an actuary to be familiar with any situation that he/she is asked to tackle. Therefore, he/she is able to factor in the certain social and cultural factors that effect his/her calculations, which brings him/her to the significant predictions that he/she is paid to find.

The surreal numbers form a field containing the reals, except for the fact that they are a proper class, not a set. The set of all surreal numbers with birthday smaller than some inaccessible cardinal number form a field.

Because each rational number can be written as a decimal, the field of rational numbers is contained in the field of real numbers. When one field is contained in another and uses the same operations, it is said to be a subfield of the larger field. In particular, the rational numbers are a subfield of the real numbers, and the real numbers are a subfield of the complex numbers. If there are only a finite number of elements in the field, the field is said to be finite; otherwise, it is said to be infinite. The rational numbers, the real numbers, and the complex numbers are all examples of infinite fields.
