希望能帮到你!
(-3)+(+7)+(-10)=7-3-10=-6
(-13)+(-29)=-(13+29)=-42
(-3.87)+(+2.98)=2.98-3.87=-0.89
(-3)+(+7)+(-10)=-3+7-10=4-10=-6
(-13)+(-29)=-(13+29)=-42
(-3.87)+(+2.98)=-(3.87-2.98)=-0.89
原式1=7-(3+10)=7-13=-(13-7)=-6 原式2=-(13+29)=-42 原式3=-(3.87-2.98)=-0.89
(-3)+(+7)+(-10)
=-3+7-10
=4-10
=-6
(-13)+(-29)
=-13-29
=-(13+29)
=-42
(-3.87)+(+2.98)
=-3.87+2.98
=2.98-3.87
=-0.89
1)原式=-3+7-10+-6
2)原式=-42
3)原式=-0.89
(-3)+(+7)+(-10)=4-10=-6
(-13)+(-29)=-42
(-3.87)+(+2.98)=2.98-3.87=-0.89
1、原式=(-3)+7-10=-6
2、原式=(-13)-29=-42
3、原式=(-3.87)+2.98=-0.89
