Answer 2

Respuesta:

a) (3-8) + [5 - (-2)]= (-5) + [5 +2] = -5 + [+7] = 2              

b) 5 - [632 - 2 (12 - 8) - 3 + 6] =  5 - [632 - 2 (4) - 3 + 6] = 5 - [632 - 8 - 3 + 6]=

    = 5 - [638 - 11]= 5- [627] = 5-627  = -622  

c) 18 / [12 / (-2)] = 18/ [-6]  = 18/-6  = -3

d) (5 + 3 * 2 / 6 - 4) * (4 / 2 - 3 + 6) = (5 + 6/ 6 - 4) * (2- 3 + 6)=

   = (5 + 1 - 4) * (-1 + 6)= (6- 4) * (+5) = (2)(5) = 10

e) (7 - 2 + 4) - (2 - 5) = (5+4) - (-3) =  (+9) + 3 = 9 + 3  = 12

f) (-12) * 3 + 18 / (-12 / 6 + 8) =  -36 + 18 / (-2 + 8) =  -36+18/6 = -36+3 = -33

g) 6 * {3 * [-9 + 4 (5 * 3 - 9)] - 3 * (40 - 8)} =  6 * {3 * [-9 + 4 (15 - 9)] - 3 * (32)} =

    =  6 * {3 * [-9 + 4 (+6)] - 96} =  6 * {3 * [-9 + 24] - 96} = 6 * {3 * [+13] - 96} =

    =  6 * {39 - 96}=  6 * {-57} = -342
