for all levels of education that joins geometry, algebra, tables, graphing,
statistics and calculus in one easy-to-use package.

features are:

• Facilitates students tracing because it stores the score, date, duration and
  construction of each of the attempts made ​​by the users.
• Students can save the state of the activities to continue them later.
