(1/2011-1) (1/2010-1).(1/3-1) (1/2-1)要说明运算过程
(1/2011-1) (1/2010-1).(1/3-1) (1/2-1)要说明运算过程
(1/2011-1) (1/2010-1).(1/3-1) (1/2-1)要说明运算过程
(1/2011-1) (1/2010-1).(1/3-1) (1/2-1)
=1/2x2/3x3/4x...x2010/2011
=1/2011
(-2010/2011)(-2009/2010)……（-2/3)(-1/2) 2~2011共2010个数故结果为正
=1/2011
(1/2011-1) (1/2010-1)......(1/3-1) (1/2-1)
=(-2010/2011)(-2009/2010)(-2008/2009).....(-2/3)(-1/2) 互相约分，共2010项
=1/2011
1/2009*2010+1/2010+1/2011
(2011+1/2009)×1/2010
2011-1/2×2011-1/3×(2011-1/2×2011)-...-1/2011×（2011-1/2×2011-...-1/2010×2011）
(2009+2008*2010)/(2009*2010-1)+(2010+2009*2011)/(2010*2011-1)+(2011+2010*201
(2012+1/2011)/(2011+1/2012)+(2010+1/2011)/(2011+1/2010）的简便方法
2010*2012*(1/2010*2011+1/2011*2012)
2010*2012*(1/2010*2011+1/2011*2012)
2010×2011×2012×2013+1
(-8)^2011*(-1/8)^2010
（-1 2010/2011）X2011
2009+2008×2010/2009×2010-1+2010+2009×2011/2010×2011-1-2011+2010×2012/2011×2012-1
(2009×2010-1)/(2009+2008×2010)+(2010×2011-1)/(2010+2009×2011)-2011+2010×2012/2011×2012-1
|1/2009-1/2010|+|1/2010-1/2011|+|1/2011-1/2012|
计算|2009/1-2010/1|+|2010/1-2011/1|+|2011/1-2009/1|
|1/2011-1/2010|-｜1/2012-1/2010｜+｜1/2012-1/2011｜=?
计算：｜1/2012-1/2011｜+｜1/2011-1/2010｜-｜1/2012-1/2010｜要解题思路
|1/2010-1/2009|+|1/2011-1/2010|-|1/2011-1/2009|=多少
|1/2009-1/2010|+|1/2010-1/2011|+|1/2011-1/2012|=
