|1/2004-1/2003|+|1/2003-1/2002|+|1/2002-1/2001|-|1/2001-1/2004|=?

前面几个绝对值后与最后这个相减等于0
再问： |1/2004-1/2003|+|1/2003-1/2002|+|1/2002-1/2001|-|1/2001-1/2004|=?最后一个符号是—
再答：没有看懂你的追问
再问：有没有过程
再答： |1/2004-1/2003|+|1/2003-1/2002|+|1/2002-1/2001|-|1/2001-1/2004|= |3/2012-4/2012|+ | 4/2012-6/2012 | + | 6/2012-12/2012 | - | 12/2012-3/2012| = 1 /12012 +2/2012+6/2012 -9/2012 =0
