A Framework to build an object oriented mathematical tool with computer algebra system (CAS) capability

Computer algebra system (CAS) applications are mathematical applications developed with the purpose of solving mathematical problems which are too difficult or even impossible to solve by hand. Modern versions of CAS applications are known for their rather large set of features such as support for graphical representations of results, symbolic manipulation, big-integer calculations, and complex-number arithmetic. The proposed idea in developing framework for a mathematical tool with CAS capability is derived from the motivation of object oriented design that integrate each application process in terms of an independent object module. Additional motivation is scalability and interface, meaning more functionality can be integrated without changing any core existed module, that is just create a new object and plug in.
