Answer 1

a) 15+ (26 - 12) - 8 = 21

b) (22 + 4)-17 +5 = 14

c) (9+ 8) + (16 - 9) = 24

d) 25 + (12 + (8 - 5) + 2) = 42

e) 32 (12-6) + 8) = 200

f) (76 - [42+(12-6) + 3) - 10) - 2 = 13

g) {[(50 - 20)-30] +20) - 10 = 10

h) 10 - {[(5 + 5)-3] - 2) = 5

i) 45+ 42 - [18+ (9- 5) +5)]= 60

j) 17+ ([26 - (15 - 8) + (8-4) - 9)=​  31

espero ter ajudado :)

Boa sorte <3
