24*25*125=4*25*3*2*125=300*250=75000
把24分成3和8 用8乘125 再乘25
125乘24乘25=125乘8乘3乘25=1000乘75=75000
25x125x24 =25x4x8x125 =100x1000 =10000
=3*8*25*30*4*125=8*125*4*25*3*30=1000*100*90=9000000
24*2*125*25 =48*125*25=6*8*125*25=(125*8)*25*6=6000*25=150000
四年级简便计算24*25*12524*25*125=125x8x(3x25)=1000x75=75000
24乘2乘125乘25=3x2x25x8x125=150x1000=150000
24*125=3*8*125=3*1000=3000
24 * 2 * 125 * 25 = 3 * 8 * 2 * 125 * 25 = 3 * (8 * 125) * (2 * 25) = 3 * 1000 * 50 = 150000
