Выполни сложение по частям, пользуясь образцом:
Образец: 27 + 49 = 27 + (40 + 9) = (27 + 40) + 9 = 67 + 9 = 76
36 + 78
45 + 17
53 + 39
38 + 24
36 + 78 = 36 + (70 + 8) = (36 + 70) + 8 = 106 + 8 = 114
45 + 17 = 45 + (10 + 7) = (45 + 10) + 7 = 55 + 7 = 62
53 + 39 = 53 + (30 + 9) = (53 + 30) + 9 = 83 + 9 = 92
38 + 24 = 38 + (20 + 4) = (38 + 20) + 4 = 58 + 4 = 62
