ALCULATOR
The QuickPAD Pro calculator can be used for expressions and functions or for plotting
graphs. The expressions program is similar to a regular hand-held calculator and can be
used to solve very basic as well as more complicated arithmetic functions. The plotter
program is based on a two-dimensional coordinate plane and can be used to represent
equations and functions graphically.

As in a standard spreadsheet, the columns and rows are labeled with letters and numbers;
letters are used for the columns and numbers for the rows. These labels are directly
correlated to the cell addresses so that if you were editing the cell in column
the cell address 10 would appear in the upper left corner of the screen. The large open
C
area within the blue border contains the user cells. You can use the arrow keys to move
from cell to cell to navigate the spreadsheet. Directly above the blue border are two
command lines. Whenever you enter a value (i.e. text, number, symbol, etc.), the typed
string will appear in the very top line on your screen. In addition, this line will display the
cell address, as mentioned above, and will also display any value previously appearing in
the selected cell. The second command line is for messages from the program. This line
will display error messages and responses to values entered by the user.
