(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

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

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

解:440×34+44×660 =44×340+44×660 =44×(340+660) =44×1000 =44000

25✖️(440-170)➗30简便运算 25✖️(440-170)➗30 =25*270÷30 =25*9 =225

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

720*56+440*72 解:简便运算 =720x56+44x720 运用乘法分配律 = (56+44)x720 =100x720 =72000 祝学习进步。
