Use time-value-of-money (TVM) functions (menu items 2
through 6) to analyze financial instruments such as
annuities, loans, mortgages, leases, and savings.
Each TVM function takes zero to six arguments, which
must be real numbers. The values that you specify as
arguments for these functions are not stored to the TVM
variables (page 14.14).
Note: To store a value to a TVM variable, use the TVM Solver (page
14.4) or use ¿ and any TVM variable on the FINANCE VARS
menu (page 14.14).
If you enter less than six arguments, the TI-83 substitutes a
previously stored TVM variable value for each unspecified
argument.
If you enter any arguments with a TVM function, you must
place the argument or arguments in parentheses.
tvm_Pmt computes the amount of each payment.

Note: In the example above, the values are stored to the TVM
variables in the TVM Solver. Then the payment (tvm_Pmt) is
computed on the home screen using the values in the TVM Solver.
Next, the interest rate is changed to 9.5 to illustrate the effect on the
payment amount.
