Вариант 2. Вычислите: 1. 27 - 13 ' (-5). 2. 15 ' (-3) + 73. 3. -23 + 35 : 5. 4. -14 ' 4 - 36. 5. -32 + 15 ' 5. 6. 17 - 14 ' 4. 7. 29 - 24 : 3. 8. -21 + 56 : 7. 9. 31 - 5 ' 16. 10. -23 + 17 ' 6.

Решение:

1. \( 27 - 13 ' (-5) = 27 + 65 = 92 \)
2. \( 15 ' (-3) + 73 = -45 + 73 = 28 \)
3. \( -23 + 35 : 5 = -23 + 7 = -16 \)
4. \( -14 ' 4 - 36 = -56 - 36 = -92 \)
5. \( -32 + 15 ' 5 = -32 + 75 = 43 \)
6. \( 17 - 14 ' 4 = 17 - 56 = -39 \)
7. \( 29 - 24 : 3 = 29 - 8 = 21 \)
8. \( -21 + 56 : 7 = -21 + 8 = -13 \)
9. \( 31 - 5 ' 16 = 31 - 80 = -49 \)
10. \( -23 + 17 ' 6 = -23 + 102 = 79 \)

Ответ: 1. 92; 2. 28; 3. -16; 4. -92; 5. 43; 6. -39; 7. 21; 8. -13; 9. -49; 10. 79.
