Answer 1

Resposta:

Explicação passo-a-passo:

1) 2 + 8-3-5 + 15 =  

25 - 8 = 17

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

12 + [35 - 12 + 2] = 12 + 25 = 37

3) [(18 + 3.2) : 8 + 5.3] 46 =

[(18+6)/8 + 15] 46 = [24/8 + 15]46 = [3+15]46 = 18 * 46 = 828

4) 37 + [-25 - (-11 + 19 - 4)] =

37 + [-25 - 4] = 37 - 29 = 8

5) 60 : {2 - [-7 + 18 - (-3 + 12)]} - [7 - (-3) - 18 (-2) + 1] =​

60 : [2-(11- 9)] - [7 + 3 + 36 + 1]

60 : 0 - [47] = ???
