12.5x64x2.5简便方法

12.5x64x2.5 =12.5x(8x2x4)x2.5 =(12.5x8)x2x(4x2.5) =100x2x10 =2000 愿对你有所帮助!

64可以分成8和8

0.5x2.5x12.5x64=0.5x2.5x12.5x(2x4x8)=(0.5x2)x(2.5x4)x(12.5x8)=1x10x100=1000

make test是测试安装环境,如果有问题的话,就会告诉你,如果报错,得看具体报的什么错,再去针对这个错误去解决

37x0.125x8 =37x(0.125x8)=37x1=37 12.5x3.4x0.8 =3.4x(12.5x0.8)=3.4x10=34 4.36x2.5+5.64x2.5=(4.36+5.64)x2.5=10x2.5=25

0.25x64x12.5 =(0.25x8)×(8x12.5) =2×100 =200

1.25*64十12.5*3十0.125*60=1.25*(64+10*3+1/10*60)=1.25*100=125

(30.5-15.64-12.36)x 0.4 =[30.5-(15.64+12.36)]×0.4 =[30.5-28]×0.4 =2.5×0.4 =1

个人觉得拍照方便上是魅蓝玩游戏的话荣耀8x好

12.5x2.5x64x0.5 =12.5x2.5x8x4x2x0.5 =12.5x8x(2.5x4)x(0.5x2) =100x10x1 =1000 谢谢,请采纳
