Pure mathematics is the study of mathematical concepts independently of any application outside mathematics. These concepts may originate in real-world concerns, and the results obtained may later turn out to be useful for practical applications, but pure mathematicians are not primarily motivated by such applications.
Mathematics is the study of numbers, shapes, and patterns. The word comes from the Greek μάθημα (máthema), meaning " science, knowledge, or learning ", and is sometimes shortened to math or maths . It is the study of: Numbers: including how things can be counted. Structure: including how things are organized, but also how they can be or ...
In mathematics, a matrix (plural: matrices) is a rectangle of numbers, arranged in rows and columns. The rows are each left-to-right (horizontal) lines, and the columns go top-to-bottom ( vertical ). The top-left cell is at row 1, column 1 (see diagram at right) . Matrices are often represented by capital roman letters such as , and , [1] and ...
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.[1] The set X is called the domain of the function[2] and the set Y is called the codomain of the function.[3] Functions were originally the idealization of how a varying quantity depends on another quantity. For example, the position of a ...
2012年3月30日 · Mathematics. The science of quantitative relations and spatial forms in the real world. Being inseparably connected with the needs of technology and natural science, the accumulation of quantitative relations and spatial forms studied in mathematics is continuously expanding; so this general definition of mathematics becomes ever richer in ...

In mathematics, a matrix ( pl.: matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or property of such an object. For example, is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a " matrix ...
