20.12×37-201.2×1.9+2012×0.82

20.12×37-201.2×1.9+2012×0.82
20.12×37-201.2×1.9+2012×0.82

20.12×37-201.2×1.9+2012×0.82
20.12×37-201.2×1.9+2012×0.82
=2012x0.37-2012x0.19+2012x0.82
=2012x(0.37-0.19+0.82)
=2012x1
=2012

计算机计算过程如下：

简便过程如下：
20.12×37-201.2×1.9+2012×0.82
=2012x0.37-2012x0.19+2012x0.82
=2012x(0.37-0.19+0.82)
=2012x1
=2012

20.12×37-201.2×1.9+2012×0.82
=20.12*37-20.12*19+20.12*82
=20.12*(37-19+82)
=20.12*100
=2012

20.12×37-201.2×1.9+2012×0.82
=20.12×37-20.12×19+20.12×82
=20.12×（37-19+82）
=20.12×100
=2012

呵呵，这个结果倒是很喜感啊。2012！
