(440(0)x(300&0)简便运算

如图

简便运算 360x56+36x440 =36x560+36x440 =36x(560+440) =36x1000 =36000

[440+(620-586)×4]÷18 =[440+46*4]/18 =(440+184)/18 =624/18 =104/3

3548-(560+2548)-440 =(3548-2548)-(560+440) =1000-1000 =0

440x0.25 =0.25x4x110 =1x110 =110 希望能帮到你

解:440.98-87.4+160.98 =(440.98+160.98)-87.4 =601.96-87.4 =514.56

440-157-143 =440-(157+143) =440-300 =140

原式=(440-170)÷30×25 =270÷30×25 =9×25 =225

370×56+37×440 =370×(56+44) =370×100 =37000 你好,本题已解答,如果满意,请点右上角“采纳答案”。

440+37+56 =440+60-4+37 =500+33 =533
