计算:2011.327×2010.328-2011.328×2010.327=______.
2011.327×2010.328-2011.328×2010.327
=2011.327×(2010.327+0.001)-(2011.327+0.001)×2010.327
=2011.327×2010.327+2011.327×0.001-2011.327×2010.327-0.001×2010.327
=2011.327×2010.327-2011.327×2010.327+2011.327×0.001-0.001×2010.327
=2.011327-2.010327
=0.001.
故答案为:0.001.
=2011.327×(2010.327+0.001)-(2011.327+0.001)×2010.327
=2011.327×2010.327+2011.327×0.001-2011.327×2010.327-0.001×2010.327
=2011.327×2010.327-2011.327×2010.327+2011.327×0.001-0.001×2010.327
=2.011327-2.010327
=0.001.
故答案为:0.001.
