Computer Algebra System (CAS)

The computer algebra system (CAS) enables you to perform symbolic calculations. By default, the CAS works in exact mode. On
the other hand, non-CAS calculations, such as those performed in Home view or by an app, are numerical calculations and often
approximations limited by the precision of the calculator (to 10

To open the CAS, press
K . The CAS view that appears is similar to the Home view. Previous
CAS calculations are recorded in history and you can re-use an expression or result in exactly the
same way: by selecting it and tapping
example, pressing
J clears the entry line, and pressing SJ clears the entire history.
The menu buttons in CAS view are:

The CAS offers many hundreds of functions, covering algebra, calculus, equation solving, polynomials, and more. You select a
function from the
menu, one of the Toolbox menus (discussed in chapter 7).
CAS settings
Various settings allow you to configure how you would like the CAS to work. To display the
