A ) 6- [ ( - 3 ) + ( - 7) ] - [ ( - 1 ) - (- 5 ) - ( - 8 )

Answer 1

  -3/4 - (-3/5) = - 3/20 = - 0,15

-7- (-3/4) =- 25/4 = - 6,25

-2 -(-5/6)= - 7/6

1/7 - 4/7= -3/7

6/11 -2= - 16/11

1/2-4/7=-1/14

-2/5-(-0,6)=1/5

 2,5-1 i 1/4=5/4

-1/8-5 i 1/3= -131/24

-20 i 5/6 -0 =-20 i 5/6

6- [ ( - 3 ) + ( - 7) ] - [ ( - 1 ) - (- 5 ) - ( - 8 )] = 6- [-3-7]-[-1+5+8]= 6+ 10-12= 4
