Modus (medieval music) In medieval music theory, the Latin term modus (meaning "a measure", "standard of measurement", "quantity", "size", "length", or, rendered in English, mode)
Time value of money the contributions of "FV", the value of cash flow at time "t": Note that this series can be summed for a given value of "n", or when "n" is ∞. This is a very general formula, which leads to several important special cases given below. In this case the cash flow values remain the same throughout the "n" periods. The present value of an annuity (PVA) formula has four variables, each of which can be solved for by numerical methods: To get the PV of an annuity due, multiply the above equation by (1 + "i"). In this case each
