automatic-compute, enter-or-compute, and settings.
When you enter a value for a variable, the calculator displays . When you
compute a value for a variable, the calculator displays . If you make a
change to a worksheet that invalidates previously entered or computed
values, the and indicators are removed. Refer to the chapters on each
worksheet to find each variable’s type. 18 Chapter 1: Overview of Calculator Operations Enter-Only Variables
For enter-only variables, you can only enter values; you cannot compute a
value for this type of variable. Values for enter-only variables may be
limited to a specified range. An enter-only variable can be:
Entered directly from the keyboard.
The result of a math calculation.
Recalled from memory.
Obtained from another worksheet using the last answer feature.
When you access an enter-only variable, the variable label and the ENTER
indicator are displayed. The ENTER indicator also reminds you that, once
you have keyed a value into the display, you must press
to assign that
value to the variable. An = sign is displayed between the label and the value
when the value has been assigned to the variable. Compute-Only Variables
For compute-only variables, you compute values by displaying the
appropriate label and pressing
; you cannot enter a value for this type of
When you access a compute-only variable, the variable label and the
COMPUTE indicator are displayed. This indicator reminds you to press to compute a value for the displayed variable. An = sign is displayed
between the label and the value when the value has been assigned to the
variable. Automatic-Compute Variables
For automatic-compute variables, you do not have to press
; a value is
automatically computed and displayed when you access the variable by
pressing or . After a value is automatically computed, an = sign is
displayed between the label and the value. Enter-or-Compute Variables in the TVM Worksheet
The five variables in the TVM worksheet (N, I/Y,...
