解答
首先是个负数
绝对值的话等于(1997/1998)(1996/1997)……(999/1000)=999/1998=1/2
所以答案是-1/2
推荐
(1/1998-1)(1/1997-1)(1/1996-1)等等(1/1001-1)(1/1000-1)=?)
(1/1998-1)*(1/1997-1)*(1/1996-1)*...*(1/1000-1)
(1998/1-1)*(1997/1-1)*(1996/1-1)*.*(1001/1-1)*(1000/1-1).
(1998/1-1)(1997/1-1)(1996/1-1).(1001/1-1)(1000/1-1).
初中数学题(1/1998-1)*(1/1997-1)*(1/1996-1).(1/1001)*(1/1000-1)
