Explicação passo-a-passo:

a. ( 10 - 5) - ( 2 + 3) =

5 - ( 2 + 3 ) =

5 - ( 5 ) =

5 - 5 = 0

b. (10+5)-(1+6 ) =

15 - ( 1 + 6 ) =

15 - ( 7 )

15 - 7 = 8

c. 7-(8-3)+1 =

7 - ( 5 ) + 1 =  

7 - 5 + 1 =

2 + 1 = 3

d. 74 + {10 - (5-(6-4) +1 ] } =

74 + {10 - ( 5 - ( 2 ) + 1 } =

74 + { 10 - ( 5 -2 + 1 ) } =

74 + { 10 - ( 4 ) } =

74 + { 10 - 4 } =

74 + { 6 } = 80

e. 32 + ( 10 - (9-4)+8)=

32 + ( 10 - ( 5 ) + 8 ) =

32 + ( 10 - 5 + 8 ) =

32 + ( 18 - 5 ) =

32 + ( 13 ) = 45

f. 20+ ( 13 + ( 10- 6) +4 ]=

20 + ( 13 + ( 4 ) + 4 ) =

20 + ( 13 + 4 + 4 ) =

20 + ( 21 ) = 41

g. 25+ { 12+(2-(8-6) + 2 ]}=

25 + { 12+(2- ( 2 ) + 2) ] =

25 +  { 12+ (2- 2 + 2 ) } =

25 +  { 12+( 2 ) } =

25 + { 14 }

25 + 14 = 39
