Chapter 2: Operating the Graphing Calculator

MATH, STAT, and PRGM Menu Keys

By using the M, S, and Pkeys, you can access many menu items for complex calculation tasks. The appendix “List of Menu/Sub-menu Items” shows the contents of each, with detailed descriptions of each sub-menu item.

Note that the contents of menu items differ drastically between the Basic keyboard and the Advanced keyboard. For example, the Pmenu for the Basic mode contains only one item (A EXEC), while in the Advanced mode there are three menu items (A EXEC, B EDIT, and C NEW).

Example

Round the following number beyond the decimal point: 34.567

1.Press #C, then

M. The MATH menu takes over the screen, as shown to the right. MATH menu items are displayed on the left side of the screen.

Note: The example above is simulated on the Basic mode. There are more menu items available with the Advanced mode.

2.Use the {and }keys to move the cursor up and down the menu. As you scroll, you will see the corresponding sub-menu contents (shown on the right side of the screen) change.

3.Set the cursor at B NUM.

Menu items can also be selected by using shortcut keys (A through H); in this example, simply press Bto select B NUM. There is no need to use Afor this operation.

4.Press a shortcut key 2 to select 2 round(. The screen now goes back to the calculation screen, as follows:

Another way of selecting the sub-menu item is to press '

(or E) on the menu item B NUM. The cursor will be extended into the sub-menu on the right. Now, move the cursor on the sub-menu down to 2 round(, then press E.
