2018*2016/2017的简便计算

2018*2016/2017的简便计算 解:采用分配律, 原式=(2017+1)x2016/2017 =2017x2016/2017+2016/2017 =2016又2016/2017

2016×2017-2018×2015 =2016*(2018-1)-2018*2015 =2016*2018-2016-2018*2015 =2018*(2016-2015)-2016 =2018-2016 =2

(201720172017-20172017-2017)/(201820182018-20182018-2018) =[2017×(100010001-10001-1)]/[2018×(100010001-10001-1)] =2017/2018

2016×2017-2015×2018 =2016×2017-2015×2017-2015 =(2016-2015)×2017-2015 =2017-2015 =2

2018x2017-2017×2016 =2017X(2018-2016) =2017X2 =4034 希望对你有帮助,满意请及时采纳, 你的采纳是我回答的动力!

2018分之2017乘以2016的简便方法是什么 2018分之2017乘以2016 =2016*(1-1/2018) =2016-1013/1014 =2015又1/1014

2016×2018 =(2017-1)(2017+1) =2017²-1

(2014+2015+2016+2017+2018)÷2016 =(2016×5)÷2016 =(2016÷2016)×5 =1×5 =5

2016÷2016又2016/2017 =(2016÷2016)÷(2016÷2016+2016/2017÷2016) =1÷(1+1/2017) =1÷2018/2017 =2017/2018
