sper ca te-am ajutat si ca nu am gresit la calcule
Explicație pas cu pas:
a). |3|-|-6|=3-(+6)=3-6=-3
b). |-4|+|-1|=4+(+1)=4+1=5
c). |6|-|-7|-|-13|=6-(+7)-(+13)=6-7-13=-1-13=-14
d). -|-12|+|-3|=-(+12)+(+3)=-12+3=-9
e). |-18|-|-23|=+18-(+23)=18-23=-5
f). -18+(-16+|-3-9|)=-18+(-16+(+12))=-18+(-16+12)=-18+(-4)=-18-4=-22
g). -3-(+17-|-19-3|)=-3-(+17-(+22))=-3-(17-22)=-3-(-5)=-3+5=2
h). -19+|-13-5+|-7-8||=-19+|-13-5+15|=-19+(+3)=-19+3=-16
