Entering Numbers and Viewing the TOTAL

To enter numbers into a SUM list:

1.Press $. You’ll see ;:H0L#T8U if the current list is empty, or ;:H0L2 or moreT8U if the list is not empty. This is the bottom of the current list.

2.If the list is empty, start filling it (step 3). If the current list is not empty, you can do either a or b:

a.Clear the list by pressing @c W(see also page 127.)

b.Get a new list by pressing ps(The old list must be named first. Press oor see page 126.)

3.Key in the value of the first item, ITEM(1) (press & for a negative number), and press I.* (To view ITEM(1) longer, hold down Ibefore releasing it.)

*Remember that you can do calculations with a number before entering it. This does not interfere with the list. Whenever you press I, the number (or evaluated expression) in the calculator line is entered into the list. If you need to use the MATH menu, just press @m, do the calculation, then press e) to return to where you were in SUM.
