Main Features

- Takes full advantage of the power and flexibility of the HP
48 by introducing a powerful interactive menu providing analysis, equation and reference
environments.
- Features adjustable scrolling speed, easy unit management,
and a user interface that can be customized.
- Easy navigability in the menu structure, friendly user input
forms, and an extensive set of tables round out the depth of the material in the card.
