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 2-14for a list of one-number functions.
