Time Value of Money (TVM), Cash Flows, Bond, and Break-even Keys
When entering data for TVM, cash flows, bond, depreciation and break-even calculations,
results are calculated based on data entered into specific memory registers. When pressed,
the keys used for these operations:
• store data.
• enter data for a variable that is used during calculations (input only).
• calculate unknown variables based on stored data.
For more information on how these keys function, refer to the specific chapters which cover
TVM problems, cash flows, and bond and break-even calculations.
Math Functions
One-Number Functions
Math functions involving one number use the number in the display. To execute one-number
functions, with a number displayed, press the key or key combination corresponding to the
operation you wish to execute. The result is displayed. See Table 2-14 for a list of one-number
functions.
Before doing any trigonometric calculations, check whether the angle mode is set for degrees
or radians (Rad). Degrees is the default setting. The RAD annunciator in the display indicates
radians is active. Press ]3 to toggle between the settings. You will need to change
the setting if the active mode is not what your problem requires.
Table 2-14 lists the one-number functions of the calculator.
]U
Sum of the y-values.
