+"""
+An ordinary annuity means making or requiring payments at the end
+of each term during a given period.
+For example, if the given period is 3 terms long and the payment
+for each term is $1000, then the cash flow is as follows:
+
+    0: no payment --- 1: $1000 --- 2: $1000 --- 3: $1000
+
+The function, get_ordinary_annuity_future_value, calculates the future value of
+the given ordinary annuity. In the example above, the function should return
+the sum of each payment's future value at the end of term 3,
+which means the sum is returned as soon as the last payment is made.
+
+More info on: https://www.investopedia.com/retirement/calculating-present-and-future-value-of-annuities
+
+This function can help to understand how much you will receive
+if you make a regular deposit at the end of each term
+for saving with a fix period and interest rate.
