12 Making Financial Calculations Easy Note: A battery symbol (¼) shown in the lower-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 E. 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 the ¼, !, 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.

Amount required to be deposited.* 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% annually, compounded semiannually. How much would it be worth by the time she enters college? In this example, we need to calculate FV, the future value.
