88X125简便计算

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

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

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

88×125 =11×8×125 =11×(8×125) =11×1000 =11000 记住一下两个公式,做题更简便: 4×25=100 8×125=1000

88x125 =(11X8)X125 =11X(8X125) =11X1000 =11000 希望对你有帮助,满意请及时采纳, 你的采纳是我回答的动力!

88x125 =11x(8x125) =11x1000 =11000

原式 =125x(80+8)x125 =125x80x125+125x8x125 =10000x125+1000x125 =1250000+125000 =1375000

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

原式 =88*125(乘法交换律) =11*(8*125)(乘法结合律) =11*1000 =11000.

125x8.88 =125x8x1.11 =1000x1.11 =1110
