Sep 28, 2016

$- 16$

#### Explanation:

When working with expressions which have different operations, always count the number of terms first.

Each term simplifies to a single answer and these are only added or subtracted in the last step.
Within each term the order of operations is:
Brackets first, then powers and roots, then multiply and divide.

$8 - 6 \left(7 - 3\right) \text{ } \leftarrow$ there are only 2 terms, keep them separate

$\textcolor{b l u e}{8} \textcolor{red}{- 6 \left(7 - 3\right)}$

$= \textcolor{b l u e}{8} \textcolor{red}{- 6 \left(4\right)}$

$= \textcolor{b l u e}{8} \textcolor{red}{- 24}$

$= - 16$
