Abstract: Investment and financing decisions require the valuation of investments and the determination of yields on investments. Necessary for the valuation and yield determination are the financial mathematics that involve the time value of money. With these mathematics, we can translate future cash flows to a value in the present, translate a value today into a value at some future point in time, and calculate the yield on an investment. The time-value-of-money mathematics allow the financial decision-maker to evaluate and compare investments and financing arrangements.
