PLISSS POMÓŻCIE MAM NA JUTRO DAJE NAJ!!!

tylko prosze o rozpisanie

Answer 1

1.

a)8-(-9)+(-11)-(+5)=8+9-11-5=1

(-21)+(-7)-(+15)-(32)=-21-7-15-32=-33

-(-13)+(-2)-(+16)+(-5)=+13-2-16-5=-10

b) [(-16)-(-4)]-(-8+6)=[-16+4]-(-2)=-12+2=-10

[-(+11)-(-6)]+(-5+8)=[-11+6]+(+3)=-5+3=-2

(-19)-[-(-18)-(+7)]+(-34)=-19-[+18-7]-34=-19-11-34=-64

-(+27)-(-26-17)+(+14)=-27-(-43)=-27+43=16

2.

a)25-(13+16)=25-29=-4

32-(-5+10)=32-(+5)=32-5=27

14+(-17+4)=14+(-13)=14-13=1

b)-42-(56-60)=-42-(-4)=-42+4=-38

-20-(16-12)=-20-(+4)=-20-4=-24

-17+(-5+10)=-17+(+5)=-17+5=-12

c)(6-10)-(-12+14)=-4-(+2)=-4-2=-6

(12-14)-(-16-25)=-2-(-41)=-2+41=39

-(6-9)-(-12+15)=-(-3)-(+3)=+3-3=0
