Q:How do I change the number of decimal places the calculator displays?

A:The procedure is described in “Decimal Places” on page 34.

Q:How do I clear all or portions of memory?

A:Cclears the calculator line. @cclears the data lists or variables accessible from the current menu. Erasing the entire contents of memory is covered in “Erasing Continuous Memory” on page 230.

Q:Why am I getting the wrong answer using the TVM menu?

A:Be sure to enter a value for all five TVM variables, even if a value is zero (as FV is for a loan without a balloon). Clearing the variables

before starting (@c ) accomplishes the same thing. Check the appropriate payment mode (mortgages and loans are typically End

mode calculations), and specify the number of payments per year

(Y). Also check that all figures for money paid out are negative (the cash-flow sign convention).

Q:Can I access the TVM menu functions from the Solver?

A:No, but you can do the same functions by copying the appropriate financial formulas into the Solver. The formulas are given starting on page 168.

Q:Can I access the data stored in my CFLO and SUM lists from the Solver?

A:Yes. See “Accessing CFLO and SUM Lists from the Solver,” page 177.

Q:How do I indicate multiplication in an equation typed into the Solver?

A:Use the multiplication key (*). You cannot use the letter ·in the ALPHA menu.

Q:What does an “E” in a number (for example, 2.51E－13) mean?

A:Exponent of ten (for example, 2.51 x 10-13). Refer to “Scientific Notation” on page 47.
