With HP Prime, you can choose whether to operate numerically in the Home view or symbolically using the CAS in the CAS view.
For example, press H and enter √8 in the Home view to see 2.828… or press K and enter the same expression in the CAS view to see 2√8

Things you can do in both CAS and Home views:
Tap an item to select it or tap twice to copy it to the command line editor
Tap and drag up or down to scroll through the history of calculations
Press Z to retrieve a previous entry or result from the other view
Press the Toolbox key b to see the Math and CAS menus as well as the Catalog
Press c to open a menu of easy-to-use templates
Press J to exit these menus without making a selection
Tap Sto ▸, Copy and Show menu buttons once to activate
RPN Note: HP Prime supports RPN entry.
In Home Settings (SH ), navigate to Entry and select RPN. These workshop materials use the default Textbook setting.
Example: Infinite Series
Suppose we wish to explore the series 1+23+45+87+169...
To begin with, we can compute the first few partial sums.
Press H to enter the Home view.
Type 1 and press E
Press e to cycle through its decimal,
proper fraction, and improper fraction forms
Continue as shown to the right until you have the first 5 partial sums
Another approach is to use lists. In the figure to the right, the List L1 is first defined to contain
the 1 st partial sum (1), followed by the numerator and denominator of the following term.
The second line adds the next term to the sum, then adds 2 to the numerator and
multiplies the denominator by 2, and stores the result back into list L1. From there, just pressing E generates the partial sums.
To use the CAS, we observe that the sum can be rewritten symbolically as:
