Evaluate: 16 + 9 ÷ 3 - 2 × 3

Simplify: $$\left[\left(26 \div \frac{4}{2}\right) \times \left\{8 \div 2 \times \frac{12 - 2}{5} \right\} \div \left\{4 \times 4 \div 3 \right\} \right]$$​

Fine the simplified value of $$\left[ \left( 17 \times 3 \right) \times \left\{ 7 \div 7 \times \left( 18 - \frac{14}{2} \right) \right\} \right]$$.​

​$$6 × \frac{1}{7}÷\frac{3}{7} + (\frac{45}{24}-\frac{2}{3}+\frac{7}{6}×\frac{2}{7})$$​​
