5.38+88.2-2.38+1.8
=5.38-2.38+(88.2+1.8)
=3+90
=93
28.38-5.34+26.3-4.66
=(28.38+26.3)-(5.34+4.66)
=54.68-10
=44.68

5.38-2.38+88.2+1.8=3+90=93
28.38+26.3-5.34-4.66=28.38+26.3-10=28.38+16.3=44.68

5.38+88.2-2.38+1.8=5.38-2.38+(88.2+1.8)=3+90=93;28.38-5.34+26.3-4.66=28.38+26.3-(5.34+4.66)=54.68-10=44.68

简算:
5.38+88.2-2.38+1.8
=(5.38-2.38)+(88.2+1.8)
=3+90
=93
28.38-5.34+26.3-4.66
=(28.38+26.3)-(5.34+4.66)
=54.68-10
