  The mathematics of human thought
As a result of his new algebra of logic, in 1849 Boole was appointed to the chair of mathematics at the newly founded University College, Cork.
Since his algebra was intended to capture some of the patterns of logical thought, his definitions of addition and multiplication had to correspond to some basic thought processes.
Moreover, it would be easier to do algebra if he could define addition and multiplication in such a way that they had many of the familiar properties of addition and multiplication of numbers, making his new algebra of thought similar to the algebra everyone was used to.

Therefore, as a ring, a field is an algebraic structure.

Algebraic numbers cannot be very closely approximated by rational and algebraic numbers (Liouville's theorem).
The problem of approximation of algebraic numbers by rational numbers is one of the more difficult problems in number theory; attempts to solve it yielded very important results, including the Thue, Thue–Siegel and Thue–Siegel–Roth theorems, but its ultimate solution is still nowhere in sight.
Algebraic numbers, which are a generalization of rational numbers, form subfields of algebraic numbers in the fields of real and complex numbers with special algebraic properties.

Most complex numbers are transcendental, because the set of algebraic numbers is countable while the set of complex numbers, and therefore the set of transcendental numbers, is not (since the union of two countable sets is countable).
==Algebraic integers== An algebraic integer is a number which is a root of a polynomial with integer coefficients (that is, an algebraic number) with leading coefficient 1 (a monic polynomial).
The name algebraic integer comes from the fact that the only rational numbers which are algebraic integers are the integers, and because the algebraic integers in any number field are in many ways analogous to the integers.

 Chessville - Misc. - Codes, etc. - Notation - Algebraic
In what follows, I will describe the most commonly used form of algebraic, which is sometimes referred to as “simple algebraic notation,” or just plain "algebraic notation," or even the parsimonious "algebraic." Then I'll mention a couple of other less-commonly used forms of algebraic notation, just in case you ever come across them.
One of the advantages of figurine algebraic notation is that it avoids the problem of different languages using different letters for some of the pieces in regular algebraic.

If an algebraic number satisfies a polynomial equation as given above with a polynomial of degree n and not such an equation with a lower degree, then the number is said to be an algebraic number of degree n.
In fact, it is the smallest algebraically closed field containing the rationals, and is therefore called the algebraic closure of the rationals.
The name algebraic integer comes from the fact that the only rational numbers which are algebraic integers are the integers, and because the algebraic integers in any number field are in many ways analogous to the integers.

For example, in a 2-dimensional space, each algebraic solution has 2 relational polar solutions; first: the "normal" solution; second: the module is negative and the angle is added a Pi.
The polar form is the set of polar factors (module and angles) that are associated to an algebraic form.
The solution polar form is formed by all sets of solution polar factors that define an algebraic form (this is the relational polar form plus the periods of each angle).

While geometry, statistics, discrete mathematics, and other fields are obviously important, the strong consensus among mathematicians at the college level is that inadequate mastery of arithmetic and algebra is the greatest impediment to success in college mathematics, whether for general education or in mathematically intensive courses of study.

 Infinitesimals and Transcendent Relations
Second, Descartes' focus on algebraic expressions as composite magnitudes directed the attention of algebra away from the solution of equations and toward the analysis of their structure and the transformations that lead from one structure to another.
He did not, he noted, need calculus to show that the circle and hyperbola did not have algebraic quadratrices, that is, that the areas of these curves or of any portion of them could not be expressed in closed algebraic form.
Nonetheless, the new forms of expression, especially those containing the symbols d and, harbored operations and relations that were not readily reducible to intuitible finite forms, and hence Leibniz' argument could at best persuade his readers, not compel their understanding.

The proof of the Bloch-Kato conjecture, first announced by Voevodsky during the highly successful BIRS 5-day workshop on Quadratic forms, algebraic groups and Galois cohomology (October 2003), is currently the topic of the year long program on at the Institute for Advanced Study in Princeton (2004/2005).
In general, the Galois cohomology set $H^1(F, G)$ formed by such classes (over a given field $F$) does not have a group structure; for this reason, it is often convenient to have well-behaved maps from this set to an abelian group.
Generic splitting fields were introduced by Amitsur and Roquette in the context of central simple algebras and by Knebusch in the context of quadratic forms.

 Simplifying Algebraic Expressions
There are many situations where you want to write a particular algebraic expression in the simplest possible form.
Although it is difficult to know exactly what one means in all cases by the "simplest form", a worthwhile practical procedure is to look at many different forms of an expression, and pick out the one that involves the smallest number of parts.

In the complex plane the axes also are referred to as real and imaginary, although both are real enough to the extent that the only way to distinguish between the two is by means of orientation: the rotation from the real to the imaginary axis proceeds counterclockwise.

Numerical solution refers to the transformation of the governing conservation equations from partial-differential form to algebraic form, algebraic expression of boundary conditions, linearization of the coupled governing equations and constitutive relations and solution of the linear systems.
Mass conservation equations for water, air, and VOC components are nearly identical in form, and therefore result in similar algebraic forms.
The conservation equation for solute or salt transport is similar in form to that of the energy conservation equation but its discretization uses a different donor-cell weighting scheme, therefore resulting in a separate algebraic form.

A Simple Introduction To Sequence Algebra
If a sequence algebraist is presented with the Euler's form, he could have mistakenly interpreted F(z) as consisting of a sequence of natural numbers starting from 0 and that there are ao copies of the integer 0, a1 copies of the integer 1, a2 copies of integer 2 and so on.
Note that although in sequence algebra, both power series and Laurent's seires are admitted, the latter form is favoured because of the ease of series expansion by algebraic packages and the clear visual division between duplicity factors (as numerator coefficients) and order indices of formal variables of z in the denominators.
It is proposed to adopt the canonical form of 1/z^i to represent the ith integer measured from the zero origin of the number sequence.
