|1/2003-1/2002|+|1/2004-1/2003|-|1/2004-1/2002| 要|1/2003-1/2002|+|1/2004-1/2003|-|1/2004-1/2002|
|1/2003-1/2002|+|1/2004-1/2003|-|1/2004-1/2002| 要
|1/2003-1/2002|+|1/2004-1/2003|-|1/2004-1/2002|
|1/2003-1/2002|+|1/2004-1/2003|-|1/2004-1/2002| 要|1/2003-1/2002|+|1/2004-1/2003|-|1/2004-1/2002|
1/2004<1/2003<1/2002,
所以,1/2003-1/2002<0,1/2004-1/2003<0,1/2004-1/2002<0
所以,
|1/2003-1/2002|+|1/2004-1/2003|-|1/2004-1/2002|
=-(1/2003-1/2002)-(1/2004-1/2003)+(1/2004-1/2002)
=-1/2003+1/2002-1/2004+1/2003+1/2004-1/2002
=0
望采纳
先去绝对值符号

|1/2004-1/2003|+|1/2002-1/2003|+.+|1/2-1|等于多少 |1/2004-1/2003|+|1/2002
2003²-2003+1/2003²-2003*2002+2002²
2002/2002又2002/2003+1/2004
2002/(2002+2002/2003)+1/2004
(-2)^2003*(1/2)^2002等于()
2003+2002+2001+、、、+3+2+1=?
(1+2+3+4.200+2001+2002)/2003
