15.32*4+4.68/0.25
=4*(15.32+4.68)
=4*20
=80
15/(0.15*0.4)

15.32*4+4.68/0.25 =15.32×4+4.68×4=4×(15.32+4.68)=80

15/(0.15*0.4)=15÷0.15÷0.4=100÷0.4=250

5.3+0.1+5.3-0.1=5.3+5.3+0.1-0.1=10.6
0.73-0.25+0.73+0.25 =0.73+0.73-0.25+0.25=1.46

27.38-5.34+2.62-4.66=27.38+2.62-(5.34+4.66)=30-10=20

你有点懒噢。不过,我还是告诉你,希望你弄懂才行。
4*(15.32+4.68)=4*20=80
15/(3/20*2/5)=15*20*5/3*2=5*10=50
2*5.3=10.6
2*0.73=1.46
(27.38+2.62)+(-5.34-4.66)=30-10=20

80 250 10.6
1.46 20
