37x102一37x2简便计算

37×102-37×2 =37×(102-2) =37×100 =3700

163×102-13×2 =163×(102-2) =163×100 =16300 这太简单了哈!

63×102-63×2 =63×(102-2) =63×100 =6300 希望我的回答对您有帮助,有问题可以追问。 满意请及时采纳,谢谢!

98x102 =98x(100+2) =98x100+98x2 =9800+196 =9996 运用了:乘法分配律

41x102 =41x(100+2) =41x100+41x2 =4100+82 =4182 采用吧!

如图

0.75x102 =0.75x100+0.75x2 =75+1.5 =76.5

=83*2*51-83*2*(51+34) =82*2*34

用简便、方法,77x102一2x72 77x102一2x72 =77*(100+2)-72*2 =77*100+77*2-144 =7700+10 =7710

乘法分配律ab+ac=a(b+c) 83x(102-2) =83x100 =8300
