__ LOS Explanation
FV Example: Given a 10% discount rate and cash flows of (starting with year 1) -1,000, -500, 0, 4,000, 3,500, and 2,000, compute the FV.
PV = -1,000, I/Y = 10, N = 5, CPT FV = 1,610.51
PV = -500, I/Y = 10, N = 4, CPT FV = 732.05
PV = 0, I/Y = 10, N = 3, CPT FV = 0
PV = -4,000, I/Y = 10, N = 2, CPT FV = 4,840.00
PV = -3,500, I/Y = 10, N =1 , CPT FV = 3,850.00
PV = -2,000, I/Y = 10, N = 0, CPT FV = 2,000.00
Total cash flow stream = $13,032.56

想請問紅色字及藍色字部分.....
1.
在計算FV時,為何不論數字正負號,在計算時皆列為正號?
(ex. 題目列-1000, 4000, 3500
但是下面算式都列成 -1000, -4000, -3500??
如果是INFLOW與OUtflow的觀念的話,應該下面計算會有正有負吧....??)而在計算PV時,不論數字正負號,在計算時都列為負號?
2.
請問為何計算FV總值為正值.....而計算PV總值為負值?
先謝了~~~
and 好腮雷啊~~個位大大
