Functions:
- Numerical and algebraic calculation:
- Calculation of fractions with a "one-touch" conversion between fractional and decimal display
- Access to all mathematical functions such as vx, xy, log x, ex, etc. using the virtual keyboard for numerical and algebraic calculations
- Calculates in degree and radian measure

- Random number generator, permutation, combinational logic
- Vector calculation: calculates the scalar and cross product
- Matrices calculation: creates matrices in a mathematical representation, adds rows and/or columns, determinants, transposition, eigenvector, eigenvalue
- E-activities:
- E-activities can be used by the teacher as a documentation tool for electronic examples and practical problems with accompanying text, mathematical formulae, 2D and 3D graphics, geometric drawing, dynamic geometry operations and tables.
- E-activities can also operate and be used as a "workbook" for students, so they can investigate problems and document their learning successes, or to solve problems using instructions or by entering notes and then to store their work in a file.
- E-activities thus bring together lines of text and calculations, dynamic geometry operation and all application menus like a written task in a standard textbook: descriptive text, using all applications by adding labelled "link strips" and dynamic geometry operations and additional note functions.
