MATH, STAT, and PRGM Menu Keys

By using the

M, S, and P keys, 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

P menu 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

B to select B

NUM. There is no need to use

A for this operation.

4. Press a shortcut key

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
