 Jasymca Jasymca  Jasymca is a symbolic calculator. It solves and manipulates equations, handles basic calculus problems, and provides a few more typical functions of computer algebra systems. The syntax is loosely related to GNUMaxima. While it is fun to play with mobile devices, it teaches the use of computer algebra systems, and may even be used to solve some real world problems   UPNCalc UPNCalc is a RPN (Reverse Polish Notation) calculator for mobile phones.
