The programs
- Loan payment with a TI-89 dialog: A dialog box asks for amount, yearly rate and years; shows the monthly payment, number of months and total interest.
- Amortization table into lists: Loan amount, yearly rate, years and an optional extra payment: builds lists of the balance after every year, shows the table, then the payment, months to pay off and total interest.
- Time value of money: leave one blank: N, I%, PV, PMT and FV in one dialog — leave the unknown BLANK (money paid out is negative, payments at period end); the rate is found by scan and bisection.
