1、0.4×125×25×0.8 =(0.4×25)×(125×0.8)=10×100=1000
2、1.25×(8+10) =1.25×8+1.25×10=10+12.5=22.5
3、9123-(123+8.8) =9123-123-8.8=9000-8.8=8991.2
4、1.24×8.3+8.3×1.76 =8.3×(1.24+1.76)=8.3×3=24.9
5、9999×1001 =9999×(1000+1)=9999×1000+9999×1 =10008999
6、14.8×6.3-6.3×6.5+8.3×3.7 =(14.8-6.5)×6.3+8.3×3.7=8.3×6.3+8.3×3.7 =8.3×(6.3+3.7) =8.3×10 =83
7、1.24+0.78+8.76 =(1.24+8.76)+0.78 =10+0.78 =10.78
8、933-157-43 =933-(157+43)=933-200=733
9、4821-998 =4821-1000+2=3823
10、I32×125×25 =4×8×125×25 =(4×25)×(8×125)=100×1000 =100000
11、2048÷268=2600+2600+2600+1248)÷26
=2600÷26+2600÷26+2600÷26+1248÷269
=100+100+100+48=348
(1)2.64×1.7-2.64×0.7=2.64×(1.7-0.7)=2.64×1=2.64
(2)31.5×1.07-3.15×0.7=3.15×10.7-3.15×0.7=3.15×(10.7-0.7)=3.15×10=31.5
(3)2.7×5.7-2.7+5.3×2.7=2.7×(5.7-1+5.3)=2.7×10=27
(4)0.625÷0.125×0.8=(0.625×0.8)×8÷(0.128×8)=0.5×8÷1=4
(5)18.6×6.1+3.9×18.6=18.6×(6.1+3.9)=18.6×10=186
(6)1.3579+3.5791+5.7913+7.9135+9.1357=(1+3+5+7+9)×1.1111
