Consider the following five series of cash flows which are assumed to occur at the end of each year:

Year	Stream #1	Stream #2	Stream #3	Stream #4	Stream #5
1	9,600	250	2,000	5,000	100
2	100	750	2,000	3,000	100
3	100	1,000	2,000	1,000	100
4	100	3,000	2,000	750	100
5	100	5,000	2,000	250	9,600

Part 1: Calculate the present value of each cash flow stream, assuming an interest rate of 7%.

Part 2: Calculate the future value, as of the end of the final year, of each cash flow stream, assuming an interest rate of 7%.

Part 3: The total of each column in the above table is $10,000. Why are the present values and the future values calculated in parts 1 and 2 above not equal to each other? Provide a short explanation of the concept being demonstrated by this scenario.
