Explicación paso a paso:
C. {5 + (8 x 3 + 6) - 7} =
C. {5 + (30) - 7} = 28
d. 17 - 10 + {14 - 3 + (5 x 8+20)} =
d. 17 - 10 + {14 - 3 + (60)} =
d. 17 - 10 + {71} = 78
e. {55 + 11 + 66 + 11 + (77 + 11 +11)} =
e. {55 + 11 + 66 + 11 + 99} = 242
f. [44 + 11 + 7] + [88 - 11 x 5] =
f. 62 + 33 = 95
g. 40 + [25 - (3 + 2)] =
g. 40 + [25 - 5] = g. 40 + 20 = 60
h. 60 + [(4 + 2) - 5] = h. 60 + [6 - 5] =
h. 60 + 1 = 61
i. 150 - [(5 - 1) - (4 - 3)] =
i. 150 - [(4) - (1)] = i. 150 - 3 = 147
j. 250 + [(7-2) + (4 - 1) + (3-2)] =
j. 250 + [5 + 3 + 1] = j. 250 + 9 = 259
