Question

Ex. 3,5 și 6 . Va rog mult

Answer 1

3.A=-6
B=7
C=2
D=13
E=-7
F=-3
G=-9
H=-3
I=3
J=-3
5.A=-2-(4-6)=-2-(-2)=-2+2=0
A=-2-4+6=-6+6=0
B=-3-(-2-5)-(8-10)=-3-(-7)-(-2)=-3+7+2=6
B=-3+2+5-8+10=6
C=-25-(-12+8)-(-5+11)=-25-(-4)-6=-25+4-6=-27
C=-25+12-8+5-11=-27
D=14-(7-3+14)-(-10+5)=14-18-(-5)=-4+5=1
D=14-7+3-14+10-5=1
6.A=(4-7)-(-11+19)=-3-8=-11
B=-(6-2)+11-19=-4-8=-12
C=27-(+49)-(18-27)+(-28)=27-49-(-9)-28=-22+9-28=-41
D=1-(2-3)-(4-5)-(6-7)-(8-9)=1-(-1)-(-1)-(-1)-(-1)=1+1+1+1+1=5
E=27-(+49)-(18-27)+(-28)=27-49-(-9)-28=-22+9-28=-41
F=1-(2-3)-(4-5)-(6-7)-(8-9)=5
