Integrating mathematics in architectural design and building construction helped in identifying new methodologies or tools that can generate unpredicted novel forms. Thus, architectural performance had developed with the involving of advanced mathematics fields and computational software. The approach of this research paper is to come up with findings on importance of mathematics in the process of form finding in art and architecture. Consequently, this study will investigate to what extent mathematics forms in architecture had actually a great effect on the architectural performance of building. A discussion of performance from the structural, environmental and aesthetical point of view will show. This will be done through describing how mathematics had been shifted from being an organizing tool into a creative tool then a generative medium.
