1.28*5.37-2.8*0.537简便
1.28*5.37-2.8*0.537简便

1.28*5.37-2.8*0.537简便
1.28*5.37-2.8*0.537
=5.37*(1.28-0.28)
=5.37*1
=5.37

1.28*5.37-2.8*0.537
=0.537*(12.8-2.8)
=0.537*10
=5.37

1.28*5.37-2.8*0.537=12.8*0.537-2.8*0.537=0.537*(12.8-2.8)=5.37

1.28*5.37-2.8*0.537
=1.28*5.37-0.28*5.37
=5.37*(1.28-0.28)
=5.37*1
=5.37
