Abstract In this paper, we study the four operations of the limit, and propose the relationship between the infinitesimal and infinite quadruple operations and the infinitive limit, and illustrate the idea of Taylor's formula combined with the equivalent infinitesimal calculation limit, and give the definition of infinitesimal order and its relationship. Prove a high-order infinitesimal, an equivalent infinitesimal theorem.
Keywords limit four arithmetic operations; Taylor's formula; Infinitesimal order; high order infinity
