Arithmetic is a branch of mathematics, or the primitive form of mathematics. It is a study of the basic properties of some digital operations. Commonly used operations include addition, subtraction, multiplication and division, and sometimes more complex operations such as exponent and square root are also included in the category of arithmetic operations. Arithmetic operations should be carried out according to specific rules.

Mathematics is the earliest subject to study quantity, structure, change and spatial model. In modern times, mathematics is a subject that studies the relationship between the form and quantity of real space by using logical forms.

Simply put, mathematics is the science of operation, including quantitative operation and graphic operation.

Graphic operation is geometry, including plane graphic operation and three-dimensional graphic operation.

Quantitative operations include specific numerical operations and algebraic operations.

Algebra refers to uncertain numbers, unknowns or symbols. Algebraic operations are symbolic operations. It is suitable for any specific number operation, and it is the generalization and extension of specific number operation.

The operation of a specific number is arithmetic.
