因为2004分之1与2003分之1的差小于0
所以原式=-1/2004+1/2003-1/2003+1/2002-1/2002+1/2001-1/2001+1/2004 =0
解释:因为2004分之1与2003分之1的差小于0,所以化去绝对值取它的相反数,-(1/2004-1/2003)=-1/2004+1/2003。依次类推。
然后就都被抵消了,最后等于零。

|1/2004-1/2003|+|1/2003-1/2002|+|1/2002-1/2001|+|1/2001-1/2004|
=1/2003-1/2004+1/2002-1/2003+1/2001-1/2002+1/2001-1/2004
=2/2001-2/2004
=2(1/2001-1/2004)
=2(3/4010004)
=2/1336668
=1/668334.
=1/2003-1/2004+1/2002-1/2003+1/2001-1/2002+1/2001-1/2004
=2/2001-2/2004
=2(1/2001-1/2004)
=2(3/4010004)
=2/1336668
=1/668334.

打开绝对值
=1/2003-1/2004+1/2002-1/2003+1/2001-1/2002+1/2001-1/2004
=2/2001
=1/2003-1/2004+1/2002-1/2003+1/2001-1/2002+1/2001-1/2004
=2/2001

原式=1/2003-1/2004 + 1/2002-1/2003 +1/2001-1/2002 + 1/2001 - 1/2004
=2/2001 - 2/2004
=6/(2001*2004)
=2/2001 - 2/2004
=6/(2001*2004)
