125x16x5的简便运算计算

125x16 =125x(2x8) =(125X8)x2 =1000x2 =2000

125x16x5 =125x8x2x5 =(125x8)x(2x5) =1000x10 =10000

125×16×5 =(125×8)×(2×5) =1000×10 =10000 你好,本题已解答,如果满意 请点右上角“采纳答案”。

125x16 =125x8x2 =1000x2 =2000

如图

125x12x16 =125x12x2x8 =(125x8)x(12x2) =1000x24 =24000

125x16x6x25 =(125×8)×(2×2×25)×3 =1000×100×3 =300000

连乘最常用的简单算法就是凑零,也就是凑整百。 可以拆成125X4X250X4X4X6,=500X1000X24=5X24X100X1000 这样就好算了,记住一些乘出来可以凑成整百的就好。 25X4=100 125X4=500 125X8=1000 差不多就这些

(125Ⅹ22十125)x16用简便方法计算 (125Ⅹ22十125)x16 =125*(22+1)*16 =125*8*(2*23) =46*1000 =46000

=125x8x(25x2) =1000x50 =50000
