- TIMES: when the cash flows are received (1,2,3,... or 2021, 2030, 2032,...).
- VALUES: the cash flows (-100, 7, 90*a,...).
- OBJECTIVE - "I want to find the average maturity": if the have both the times and the values without any unknown parameter.
- OBJECTIVE - "I have the average maturity, I want to find other stuff": select it if you have the maturity and you want to find the value at time 5. Then put in the "Average maturity" the maturity that you have and put in the value at time 5 an "x" or any letter, because you have to find it. It will give you the "x" or the letter you put in.
