Решение:
- 45 + 27 : 3 - 12 = 45 + 9 - 12 = 54 - 12 = 42
- 90 - 36 : 3 * 2 = 90 - 12 * 2 = 90 - 24 = 66
- 84 : 4 * 3 + 2 = 21 * 3 + 2 = 63 + 2 = 65
- 100 - 10 * 9 - 8 = 100 - 90 - 8 = 10 - 8 = 2
- 17 + 15 * 3 * 0 = 17 + 45 * 0 = 17 + 0 = 17
- 5 * 5 + 75 : 5 = 25 + 15 = 40
Ответ: 42; 66; 65; 2; 17; 40.
