Answer 1

Explicação passo-a-passo:

a-2+8-3-5+15

10-3-5+15

7-5+15

2+15=17

b-12+[35-(10-2)+2]

12+[35-8+2]

12+[35-10]

12+25=37

c-[(18+3•2)+8+5•3]+6

[(21.2)+8+5.3]+6

[42+13.3]+6

55.3+6

165+6=171

d) 37+[-11+19-4)]

37+[30-4]

37+34=71

f-8+{-5+[(8-12)+(13-12)]-10}

8+[5+[4+1]-10}

8+5+5-10

8+20=28
