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.
3.2.1.
Getting
Started
The calculator can be accessed from the QuickPAD Pro main menu by highlighting the
CALCULATOR box, or by pressing the
F
2 key. Once inside the calculator application,
you will notice three main choices at the top of your screen: (E)xpressions, (P)lotter and
(S)ettings. Press
E
to begin the expression calculator,
P
to enter the graphing calculator, or

to adjust general settings.

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
C
, row 10,
the cell address
C
10 would appear in the upper left corner of the screen. The large open
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.
