7.0.33-(-0.33)-0.33+(0.33)
求各位帮个忙了、、、
第五提打错啦
=应该是+
我要的是过程、不是仅仅要答案

1.-0.73+(-3.4)-(+5.6)+(-0.27)
=-0.73-3.4-5.6-0.27
=(-0.73-0.27)-(3.4+5.6)
=-1-9
=-10
2.-1008+(1000)-(-1008)+1000
=-1008+1000+1008+1000
=2000
3.-(-68)-(+0.75)-(-五分之三)-(+3)
=68-0.75+0.6-3
=64.85
4.(+3.15)-(0.45)+6.34+4.38-0.72+(-10)
=3.15-0.45+6.34+4.38-0.72-10
=2.7+6.34+4.38-0.72-10
=9.04+4.38-0.72-10
=13.42-10.72
=2.7
5.10101-(-101)=20132+(10130)+(-102)
=10101+101-20132+10130-102
=10101+10130-20132+101-102
=20231-20133
=98
6.775+(-75)+(300)-(-700)
=775-75+300+700
=700+1000
=1700
7.0.33-(-0.33)-0.33+(0.33)
=0.33+0.33-0.33+0.33
=0.66
