ITEM(3) and the new, updated total appear.
5. Continue entering values for ITEM(3), ITEM(4), etc. The calculator
recognizes the end of the list when an item is left blank (no value is
entered).
6. Press
e
to end the list and restore the SUM menu. You can now
proceed to correct the list, name the list, get another list, or do
statistical calculations.
Use these same instructions to enter additional lists.
Viewing and Correcting the List
To display a particular list, use
p
(see page 127).
The
[
and
]
keys move up and down the list one number at a time.
@[
and
@]
display the beginning and end of the list.
Changing or Clearing a Number. To change a number after it’s been
entered: display the number, key in the new value, and press
I
.
Use the same method to clear a number to zero. (Do not press
C
or
<
, which clears the calculator line.)
Inserting Numbers into a List. Insertion occurs before (or above) the
current entry. Pressing
m
inserts a zero item and renumbers the rest
of the list. You can then enter a new value.
For example, if ITEM(6) is in the display, pressing
m
puts a new,
zero item between the previously numbered ITEM(5) and ITEM(6).
