0.4×32313133353236313431303231363533e4b893e5b19e31333339656365125×25×0.8
=(0.4×25)×(125×0.8)
=10×100=1000

1.25×(8+10)
=1.25×8+1.25×10
=10+12.5=22.5

9123-(123+8.8)
=9123-123-8.8
=9000-8.8
=8991.2

1.24×8.3+8.3×1.76
=8.3×(1.24+1.76)
=8.3×3=24.9

9999×1001
=9999×(1000+1)
=9999×1000+9999×1
=10008999

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

1.24+0.78+8.76
=(1.24+8.76)+0.78
=10+0.78
=10.78

933-157-43
=933-(157+43)
=933-200
=733

4821-998
=4821-1000+2
=3823

I32×125×25
=4×8×125×25
=(4×25)×(8×125)
=100×1000
=100000

9048÷268
=(2600+2600+2600+1248)÷26
=2600÷26+2600÷26+2600÷26+1248÷269
=100+100+100+48
=348

2881÷ 43
=(1290+1591)÷ 434
=1290÷43+1591÷43
=30+37
=67
