25X16X125 =25X4X4X125=100X500=500000或25X16X125 =25X2X8X125=50X1000=500000常见化简算式:125X8=100025X4=100

=25x4x4x125=100x500=50000

=25*4*4*125=100*500=50000

25*16 *125;=25*2*8*125;=(25*2)*(8*125);=50*1000;=50000;

25*16x125=25x2x8x125=50x1000=50000

的简便方法计算25x16x125x7=(25*2*7)*(8*125)=350*1000=350000

25*16*125简便计算=(25*4)*(4*125)=100*500=50000.

25*16*125=25x(4x4)x125=(25x4)x(125x4)=100x500=50000

=(25乘4)(4乘125)=100乘500=50000
