2016 2017

=2016×(1-1/2017);=2016-2016/2017;=2015+1/2017

2016x20172017-2017x20162016 =2016x20172017-2017x10001x2016 =2016x20172017-20172017x2016 =2016x(20172017-20172017) =2016x0 =0

原式 =2016x2017x10001-2017x2016x10001 =2016x2017x(10001-10001) =2016x2017x0 =0

丙申,丁酉

原式=2016×(2017×10001)-2017×(2016×10001)=0

(1+2+3+4+5+…+2016+2017)2017 =[(1+2017)x2017÷2]÷2017 =2018÷2 =1009

2016×20172017-2017×20162017 =2016×20172017-2017×20162016-2017×1 =2016×2017×10001-2017×2016×10001-2017 =-2017

主要是应用平方差公式, 2016有平方,对吗? 2016^2-2015×2017 =2016^2-(2016-1)(2016+1) =2016^2-(2016^2-1) =2016^2-2016^2+1 =1。

今年的吧,猴子是去年出的,不可能当年就返常。下面介绍别的还有太乙真人应该是今年的,

2016/2016又2017分之2016 =2016/[(2016x2017+2016)/2017] =2016 x 2017/(2016x2017+2016) =2017/(2017+1) =2017/2018
