Question

A) [(-16)-(-4)]-(-8+6)=

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

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

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

2 Opuść nawiasy i oblicz :

a) 25-(13+16)= b) -42-(56-60)=

32-(-5+10)= -20-(16-12)=

14+(-17+4)= -17+(-5+10)=

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

(12-14)-(-16-25)=

-(6-9)-(-12=15)=

Prosze żeby nie był sam wynik tylko całe rozwiazanie .

Answer 1

 [(-16) - (-4)] - (-8+6)=-16+4+8-6=-12+2=-10
[- (+11) - (-6)] + (-5+8)=-11+6-5+8=-5-5+8=-10+8=-2
(-19)-[-(-18)-(+7)]+(-34=-19-18-7=-44
-(+27)-(-26-17)+(+14)=-27+26+17+14=30

 

 

25-(13+16) = 25 -29 = -4
32 -(-5+10) = 32 - 5 =27
14 + (-17+4) = 14 -13 = 1
 -42-(56-60) = -42 - (-4) = -42 + 4 = -38
-21-(16-12) = -21 - 4 = -25
-17 + (-5+10) = -17 + 5 = -12
(6-10)-(12+15)=-4-27=-31

(12-14)-(-16-25)=-2+16+25=39
-(6-9)-(-12+15)=3+12-15=0 

Answer 2

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

[-(+11)-(-6)]+(-5+8)= (-(17))+(-3)= -20

 

2

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

32-(-5+10)=   32-5= 27

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

b  -42-(56-60)=  -42-(-4)= -38

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

 -17+(-5+10)= -17+5=-12

c  (6-10)-(-12+14)= -4 -2= -6

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

 -(6-9)-(-12=15)= -(-3)-(3)= 3-3= 0
