1. \(5+6.3-44:4+2=5+18-11+2=14\)
2. \(2+3.(10^2-11)=2+3.(100-11)=2+3.(89)=2+267=269\)
3. \(5+10.10-50:5+3=5+100-10+3=98\)
4. \(4+2.6-20:2+7=4+12-10+7=13\)
5. \(-27:9+45:(-5)=-3+(-9)=-12\)
6. \(70-10:5+16=70-2+16=84\)
7. \(\dfrac{8}{7}-\dfrac{6}{7}\cdot\dfrac{11}{6}= \dfrac{8}{7}-\dfrac{6\cdot 11}{7\cdot6}= \dfrac{8}{7}-\dfrac{11}{7}= \dfrac{8-11}{7}= \dfrac{-3}{7}\)
8. \(8.5^2+(8.5)^2=8.5^2+(40)^2=8.25+1600=200+1600=1800\)
9. \(7+6.10^2-4=7+6.100-4=7+600-4=603\)
