Abstract: This article is to achieve the muti-directional computing of real number models, based on multi-directional computation of Unit group models. The research on multi-direction computation is based on and supported by the group theory and the graph theory. A abstract algebra group composed of one element is the highest abstraction of the mathematical models researched in this paper. The aprovement of multi-directional computation of the group is finished in this paper. Mathematical models in real number domain applied multi-directional computing of one element group and those are widely used in the scientific computing and the engineering computing. A software system, named Jiuzhang , was established based on these researches. Jiuzhang deals with mathematical model composed of elementary algebra operations and performing multi-directional computation on the mathematical model. The key characteristic of Jiuzhang is that it is able to perform multi-directional computation on the mathematical model. Draw out the mathematical model from the application program and performed by Jiuzhang with the performance of multi-directional usage of the mathematical model.
