用简便方法计算:125x32一125x24

原式 =125x(32-24) =125x8 =1000

原式 =125x8x4-125x8x3 =1000x4-1000x3 =4000-3000 =1000 或者: 125x(32-24) =125x8 =1000

125x4X8

125X32x24 =(125×8)×(4×24) =1000×96 =96000

125x32-125x24 =125x(32-24) =125x8 =1000 谢谢,请采纳

89x5十11x5 =(89+11)x5 =100x5 =500 25x24 =25x(4x6) =(25x4)x6 =100x6 =600 44x25 =(11x4)x25 =11x(4x25) =11x100 =1100 125x16x2222 =125x(8x2)x2222 =(125x8)x(2x2222) =1000x4444 =4444000 25x32x125x17 =25x(4x8)x125x17 =(25x4)x(8x125)...
