Mathematics is the study of structures which come from logic. Mathematics is important to the many sciences because it provides rigorous methods for developing models of complex phenomena. Examples of such phenomena include the spread of computer viruses on a network, the growth of tumors, the risk associated with certain contracts traded on the stock market, and the formation of turbulence around an aircraft. Mathematics provides a kind of "quality control" for the development of trustworthy theories and equations which are important to people in most modern technical disciplines such as engineering and economics.

Modern mathematics is built around a system of axioms, which is a name given to statements in mathematics which are given to be true. Mathematicians then use various methods of formal proof to extend the axioms to come up with surprising and elegant results. Such methods include induction and contradiction, for example.
Mathematical Subject Classification
There are numerous categories and subcategories of mathematics, as shown by the American Mathematical Society's Mathematics Subject Classification scheme.
A common way of classifying mathematics is into pure mathematics, mathematics studied in order to make mathematics more stable and powerful, and applied mathematics, taking techniques from pure mathematics and using them to develop models of "the real world." Pure mathematics is often considered to be divided into the areas of Higher Algebra, Analysis, and Topology. Applied Mathematics is sometimes considered to be divided into the areas of Dynamical Systems, Approximation Techniques, probability and statistics. There are also various applied mathematical disciplines which use a combination of these areas but focus on a particular type of application. Examples include mathematical physics and mathematical biology.
Arithmetic
- Main article: Arithmetic
Arithmetic is a branch of mathematics studying the evaluation of expressions in simplest form. In general, more basic properties of the integers belong to arithmetic while deeper or more difficult results belong to number theory, but the boundary is not extremely clear. For instance, modular arithmetic might be considered part of arithmetic as well as part of number theory.
Algebra
- Main article: Algebra
In mathematics, algebra can denote many things. As a subject, it generally denotes the study of calculations on some set. In high school, this can the study of examining, manipulating, and solving equations, inequalities, and other mathematical expressions. Algebra revolves around the concept of the variable, an unknown quantity given a name and usually denoted by a letter or symbol. Many contest problems test one's fluency with algebraic manipulation.
Algebra can be used to solve different types of equations, but algebra is also many other things
Modern algebra (or "higher", or "abstract" algebra) deals (in part) with generalisations of the normal operations seen arithmetic and high school algebra. Groups, rings, fields, modules, and vector spaces are common objects of study in higher algebra.
Algebra can be used to solve equations as simple as 
but in some cases so complex that mathematicians have not figured how to solve the particular equation yet.
As if to add to the confusion, "algebra" is the name for a certain kind of structure in modern algebra.
Modern algebra also arguably contains the field of number theory, which has important applications in computer science. (It is commonly claimed that the NSA is the largest employer in the USA of mathematicians, due to the applications of number theory to cryptanalysis.) However, number theory concerns itself with a specific structure (the ring 
), whereas algebra in general deals with general classes of structure. Furthermore, number theory interacts more specifically with certain areas of mathematics (e.g., analysis) than does algebra in general. Indeed, number theory is traditionally divided into different branches, the most prominent of which are algebraic number theory and analytic number theory.
History of Mathematics
- Main article: History of mathematics
Mathematics was noted by the earliest humans. Over time, as humans evolved, the complexity of mathematics also evolved. There was an astounding discovery on how the numbers correlated with each other, as well as in nature, so well, as they created the concept of numbers. Many cultures throughout the world contributed to the development of mathematics in historical times, from China and India to the Middle East and Greece.
Modern Mathematics began in Europe during the Renaissance, after various Arabic texts were translated into European languages during the 12th and 13th centuries. Islamic cultures in the Middle East had preserved various ancient Greek and Hindu texts, and had furthermore extended these old results into new areas. The popularity of the printing press combined with the increasing need for navigational accuracy as European powers began colonizing other parts of the globe initiated a huge mathematical boom, which has continued to this day.
