88x125 计算

解:88x125 =8x125x11 =1000x11 =11000 分析:本题简便计算的关键在于要利用8x125=1000的常用式子,然后将88分解成8x11.而后就可算出结果是11000.

88x125 =(80+8)×125 =80×125+8×125 =10000+1000 =11000

原式 =11x8x125 =11x1000 =11000 或者: =(80+8)x125 =80x125+8x125 =10000+1000 =11000

原式 =(80+8)x125 =80x125+8x125 =10000+1000 =11000 或者 =11x8x125 =11x1000 =11000

88x125怎样简便算法 =(80+8)x125 =80x125+8x125 =10000+1000 =11000

=111×8×125 =111×1000 =111000 =888×125×8÷8 =888×1000÷8 =111000

88x125 =11x8x125 =11x1000 =11000

88x125-8x125 解:运用乘法分配律 =(88-8)x125 =80x125 =10000 祝学习进步。

88x125 =11x8x123 =11x(8x125) =11x1000 =11000 记住:125x8=1000, 25x4=100

88×125 =11x(8x125) =11x1000 =11000 请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!谢谢管理员推荐采纳!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果没有明白,请追问。谢谢。
