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 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.
