3. Действия с десятичными:

1. \( -5 - 6 = -11 \)
2. \( -5 + 4 = -1 \)
3. \( -9 + 13 = 4 \)
4. \( 438 - 439 = -1 \)
5. \( -428 - 49 = -477 \)
6. \( -112 - 52 = -164 \)
7. \( 26 \cdot ( -7 ) = -182 \)
8. \( -3 + 55 = 52 \)
9. \( -8 \cdot (-2) = 16 \)
10. \( 5 \cdot (-12) = -60 \)
11. \( 4 \frac{1}{3} + 17 \frac{2}{3} = \frac{13}{3} + \frac{53}{3} = \frac{66}{3} = 22 \)
12. \( -4 \frac{2}{3} - 7 \frac{1}{6} = -\frac{14}{3} - \frac{43}{6} = -\frac{28}{6} - \frac{43}{6} = -\frac{71}{6} = -11 \frac{5}{6} \)
13. \( -4 \frac{3}{4} - 7 \frac{9}{10} = -\frac{19}{4} - \frac{79}{10} = -\frac{95}{20} - \frac{158}{20} = -\frac{253}{20} = -12 \frac{13}{20} \)
14. \( 2 \frac{1}{3} - 3 \frac{3}{5} = \frac{7}{3} - \frac{18}{5} = \frac{35}{15} - \frac{54}{15} = -\frac{19}{15} = -1 \frac{4}{15} \)
15. \( 2 \frac{7}{9} - 3 \frac{5}{6} = \frac{25}{9} - \frac{23}{6} = \frac{50}{18} - \frac{69}{18} = -\frac{19}{18} = -1 \frac{1}{18} \)
16. \( -3 \frac{1}{2} \cdot \left( -\frac{57}{64} \right) = \frac{7}{2} \cdot \frac{57}{64} = \frac{399}{128} = 3 \frac{15}{128} \)
