Step-by-step explanation:

(a-b)+c

case 1

a=0.5 , b=2 , c=-1

(0.5-2)-1 = -1.5 - 1

= -2

case 2

a=3 , b=-4 , c=-2

(3+4) -2 = 7 - 2

= 5

case 3

a=-8 , b=5 , c=3

(-8+5)+3 = -3+3

= 0

-(a-b)-c

case 1

a=0.5 , b=2 , c=-1

-(0.5-2)+1 = -(-1.5)+1

= +1.5 + 1

= 2.5

case 2

a=3 , b=-4 ,c=-2

-(3+4)+2 = -(7) +2

= -5

case 3

a=-8 , b=5 , c=3

-(-8-5) -3 = -(-13) -3

= +13 -3

= 10
