A) +3-18+22-8= -15+22-8=7-8= -1
B)+23-58+13=-35+13= -22
C)-9-17+4-8+13= -26+4-8+13=-22-8+13=-30+13=-17
D) +7-5-12=+2-12=-10
E)9-(-3)+4+3=9+3+4+3=19
F)8-(5-(-5))=8-(5+5)=8-10=-2
G)17-(2-9)= 17-(-7)=17+7=24
H)47+(-14-36)=47+(-50)= 47-50=-3
I) -37+(-3+(5-75))=-37+(-3-70)=-37-73=-110..
Cred ca nu am gresit la calcule :)
