101x57的简便箅法

101x57=100x57+1x57=5700+57=5757 以上就是简便计算过程.

原式=57(101-1) =57*100 =5700

1.01x57=57+0.01x57=57.57

101x57=(100+1)x57=5700+57=575799x63=(100-1)x63=6300-63=62379x25+25=9x25+25x1=25x(9+1)=25x10=25024x25=4x25x6=100x6=600

4.7x101=4.7x(100+1)=4.7x100+4.7=470+4.7=474.7

你好 简便计算过程如下98*101=98*(100+1)=98*100+98*1=9800+98=9898 望采纳

=(100+1)*67=100*67+1*67=6700+67=6767

可以用乘法分配律进行简便计算101*74=(100+1)*74=100*74+1*74=7400+74=7474

87*101 =87x(1oo+1) =87x100十87 =8700+87 =8787

57x100x57 =(50+7)x(50+7)x100 =(2500+700+49)x100 =3249x100 =324900
