Note: A battery symbol ( ) shown in the upper-left corner of the display
when the calculator is on signifies that the available battery power is nearly
exhausted. To install new batteries, refer to Appendix F.
The calendar functions and nearly all of the financial functions take some
time to produce an answer. (This is typically just a few seconds, but the¼,
!, L, and S functions could require a half-minute or more.) During
these calculations, the word running flashes in the display to let you know
that the calculator is running.

Example 2:
We now need to determine how to accumulate the required deposit
by the time your daughter enters college 14 years from now. Let’s say that she has
a paid-up $5,000 insurance policy that pays 5.35%, compounded annually. How
much would it be worth by the time she enters college
?
In this example, we need to calculate FV, the future value.
