Answer 1

Răspuns:

3.a) 101-[43-(11-8)+61]=101-(43-3-61)=101-(40-63)=101-(-23)=124

b) [-12-(17-15)+4]+10 = (-12-2+4)+10=(-10+4)+10=-6+10=4

c) - 21+[-57-(-39+5-18)]+26=-21+[-57-(-34-18)]+26=-21+(-57-(-52))+26=-21+(-109)+26=-88+26 =-62

d) -14-{-41-[-17+8-(15-9)]+27}+13 = -14-[-41-(-9-6)+27]+13 = -14-(-41-(-3)+27)+13=-14-(-44+27)+13=-14-(-17)+13=-31+13=-18

4.a) |7-5|+19+|21-29|-8=|2|+19+|8|-8=21+0=21

b) -|-13-2|+|2-7|+|-10|=-|11|+|5|+|10|=11+5+10=16+10=26

c) ||9-11|-|-1+16||+|-13|=|2-17|+|13|=|15|+|13|=15+13=28

d) (-17+5)+|2-14|+|-34|-34=-12+|12|+|34|-34=0+0=0

Sper sa fie bine!
