In mathematics, wholeness refers to a collection or wholeness of objects. It is composed of many parts, but in some cases, the whole itself can also be regarded as a single entity. The whole is a very important concept in mathematical research, which can be used to describe some complex phenomena, such as the nature of sets, the volume and mass in geometric space, and the force and energy in physics.

In algebra, the concept of the whole is very important. The whole can refer to any set or object in mathematics, such as matrix, vector, etc. The whole is widely used in algebra, including algebraic equations, matrix operations, vector spaces and so on. In these application fields, the whole can be regarded as an independent entity, and its parts can be regarded as attributes or variables of the whole, thus simplifying the analysis process of the problem.

In geometry, the concept of the whole is also very important. The whole can refer to a geometric figure, such as a cube, a cylinder, etc. The whole is also widely used in geometry, including geometric volume, geometric center, geometric distance and so on. In these application fields, the whole can be regarded as an independent entity, and its parts can be regarded as attributes or variables of the whole, thus facilitating the solution and research of problems.
