$\begin{lgathered}\huge{\underline{\color{orange}{\textsf{\textbf{Solution}}}}} \\\end{lgathered}$

$10-[8 - 9+{2 * 5 - (6+8* - 7 + 5)}]$

$→ 10 -[8 - 9 +{2 × 5 - (6 + 8 (-7) + 5)}]$

$→ 10 -[8 - 9 +{2 × 5 - (6 - 56 + 5)}]$

$→ 10 -[8 - 9 +{2 × 5 - (11 - 56}]$

$→ 10 - [8 - 9 +{2 × 5 - 45}]$

$→ 10 - [8 - 9 +{10 - 45}]$

$→ 10 - [8 - 9 - 35]$

$→ 10 - [8 - 44]$

$→ 10 - [36]$

$→ - 26$
