  1. \(-13-5.(-10-20)+6=-13-5.(-30)+6=-13-(-150)+6=143\)
  2. \(2.2^2+(2.2)^2=2.2^2+(4)^2=2.4+16=8+16=24\)
  3. \(9+5.(7^2-12)=9+5.(49-12)=9+5.(37)=9+185=194\)
  4. \(-81:9+72:(-8)=-9+(-9)=-18\)
  5. \(9-\sqrt{1233-7.12^2}=9-\sqrt{1233-7.144}=9-\sqrt{1233-1008}=9-\sqrt{225}=9-15=-6\)
  6. \(10+3-12.(-5)=10+3+60=73\)
  7. \(7.(-9)-8.(-10)-10=-63+80-10=7\)
  8. \(\sqrt{\dfrac{4}{49}}-\left(\dfrac{5}{14}\right)^2= \dfrac{2}{7} - \dfrac{25}{196}= \dfrac{56}{196} - \dfrac{25}{196}= \dfrac{31}{196}\)
  9. \(-56:8+48:(-6)=-7+(-8)=-15\)
  10. \(6.(-3)-3.(-7)-6=-18+21-6=-3\)
  11. \(9+8.8-6:3+5=9+64-2+5=76\)
  12. \(18+126:(-9)=18+ (-14)=4\)
