The theory of limited numbers says that the number is not infinite, that is, the number is limited in parts or completely. To reach a conclusion about the limited number, it is necessary to understand the meaning of mathematics and varied spaces, therefore, it is necessary to understand that mathematics and spaces interact. Mathematics has the function of describing the world precisely, where numbers represent elements or facts that rationally belong to space, and spaces have different intensities of specific physical concepts in each space; therefore, there is no infinite element or fact due to the differences in the intensities of specific physical concepts in spaces that do not allow the fact or fact in all spaces. To better understand this study it is necessary to read the articles: theory of obligatory necessity and equations and their effects.
