Smile I want to sell my calculator app

Hi,everyone!
I'm a student in China, I'm studing in the University which held the programming contest.I've developed a Calculator which implements most
functions of Casio fx-991es(http://www.voidware.com/calcs/fx991es.htm) except nature display and its function mostly like HiCalc
(http://www.ppclink.com/?ppclink=product&do=view&id=44).
It can calculate in binary,deciaml,octal,hex and solve trigonometric function with degree,randian,gradient and so on.Of course,it can
plot a function's image,and the image can zoom in or zoom out and can be moved.
Especially,it can solve most of the matrix problem, such as multiply,tranpose,inverse,eigenvalue,eigenvector,d eterminant,rank etc.
And it can solve nth-degree equation and nth-order linear equations.Fianlly,there is a funny game like this
