Ответ:

  1. \(|5|+|-3|=5+3=8\).
  2. \(|-4|-|-10|=4-10=-6\).
  3. \(|-3|+|-6|=3+6=9\).
  4. \(|-1.6|+|-\frac{1}{4}|=1.6+0.25=1.85\).
  5. \(-2.6+3\frac{3}{5}=-2.6+3.6=1\).
  6. \(\frac{1}{2}-(-0.5)=0.5+0.5=1\).
  7. \(-5.8-(-4.9)=-5.8+4.9=-0.9\).
  8. \(-1\frac{1}{5}\cdot(-0.6)=-1.2\cdot(-0.6)=0.72\).
  9. \(-0.7\cdot(-0.1)=0.07\).
  10. \(15-(-3)=15+3=18\).
  11. \(-10-5=-15\).
  12. \(-5+5=0\).
  13. \(-1.3:(-1\frac{1}{2})=1.3:1.5=\frac{13}{15}\).
  14. \(-\frac{3}{5}:(-\frac{15}{4})=\frac{3}{5}\cdot\frac{4}{15}=\frac{4}{25}=0.16\).
