Simplify the expression, $$25 - \left[ {16 - \left\{ {14 - \left( {18 - \overline {8 + 3} } \right)} \right\}} \right]$$

$$\eqalign{ & 25 - \left[ {16 - \left\{ {14 - \left( {18 - \overline {8 + 3} } \right)} \right\}} \right] \cr & = 25 - \left[ {16 - \left\{ {14 - \left( {18 - 8 - 3} \right)} \right\}} \right] \cr & = 25 - \left[ {16 - \left\{ {14 - \left( {18 - 11} \right)} \right\}} \right] \cr & = 25 - \left[ {16 - \left\{ {14 - 7} \right\}} \right] \cr & = 25 - \left[ {16 - 7} \right] \cr & = 25 - 9 \cr & = 16{\text{ Answer}} \cr} $$
