1-1-3 Keys k Key Markings Many of the calculator’s keys are used to perform more than one function. The functions marked on the keyboard are color coded to help you find the one you need quickly and easily. Function Key Operation 1 log l 2 10x !l 3 B al The following describes the color coding used for key markings. Color # Key Operation Orange Press ! and then the key to perform the marked function. Red Press a and then the key to perform the marked function.
1-2-1 Display 1-2 Display k Selecting Icons This section describes how to select an icon in the Main Menu to enter the mode you want. u To select an icon 1. Press m to display the Main Menu. 2. Use the cursor keys (d, e, f, c) to move the highlighting to the icon you want. Currently selected icon * The above shows the ALGEBRA FX 2.0 PLUS screen. 3. Press w to display the initial screen of the mode whose icon you selected. Here we will enter the STAT Mode.
1-2-2 Display Icon Mode Name Description GRaPH-TaBLe Use this mode to store functions, to generate a numeric table of different solutions as the values assigned to variables in a function change, and to draw graphs. DYNAmic graph Use this mode to store graph functions and to draw multiple versions of a graph by changing the values assigned to the variables in a function.
1-2-3 Display k About the Function Menu Use the function keys (1 to 6) to access the menus and commands in the menu bar along the bottom of the display screen. You can tell whether a menu bar item is a menu or a command by its appearance. • Command (Example: ) Pressing a function key that corresponds to a menu bar command executes the command. • Pull-up Menu (Example: ) Pressing a function key that corresponds to a pull-up menu opens the menu.
1-2-4 Display k Normal Display The calculator normally displays values up to 10 digits long. Values that exceed this limit are automatically converted to and displayed in exponential format. u How to interpret exponential format 1.2 E+12 indicates that the result is equivalent to 1.2 × 1012. This means that you should move the decimal point in 1.2 twelve places to the right, because the exponent is positive. This results in the value 1,200,000,000,000. 1.
1-2-5 Display k Special Display Formats This calculator uses special display formats to indicate fractions, hexadecimal values, and degrees/minutes/seconds values. u Fractions 12 .................

1-8-1 When you keep having problems… 1-8 When you keep having problems… If you keep having problems when you are trying to perform operations, try the following before assuming that there is something wrong with the calculator. k Getting the Calculator Back to its Original Mode Settings 1. From the Main Menu, enter the SYSTEM Mode. 2. Press 5(Reset). 3. Press 1(S/U), and then press w(Yes). 4. Press m to return to the Main Menu.
1-8-2 When you keep having problems… k Low Battery Message If either of the following messages appears on the display, immediately turn off the calculator and replace main batteries or the back up battery as instructed. If you continue using the calculator without replacing main batteries, power will automatically turn off to protect memory contents. Once this happens, you will not be able to turn power back on, and there is the danger that memory contents will be corrupted or lost entirely.
