$12$

#### Explanation:

There are $2$ terms in this expression. Determine an answer for each term.

Within each term, calculate the brackets first.
Then powers and roots (none in this case)
Then multiplication and division

$\textcolor{b l u e}{\left[- 4 - 28 \div \left(- 4 - 3\right)\right]} \textcolor{red}{- 3 \left(- 4\right)}$
$\textcolor{w h i t e}{w w w w w w w w w w w} \downarrow \textcolor{w h i t e}{w w w w} \downarrow$
$= \textcolor{b l u e}{\left[- 4 - 28 \div \left(- 7\right)\right]} \text{ } \textcolor{red}{+ 12}$
$\textcolor{w h i t e}{w w w w w w w w} \downarrow$
=color(blue)([-4" "+4]" "color(red)(+12)

$= \textcolor{b l u e}{0} \text{ } \textcolor{red}{+ 12}$

$= 12$

$\left[- 4 - 28 \div \left(- 4 - 3\right)\right] - 3 \left(- 4\right) = 12$

#### Explanation:

Use order of operations (PEMDAS).
$\left[- 4 - 28 \div \left(- 4 - 3\right)\right] - 3 \left(- 4\right)$
$\left[- 4 - 28 \div \left(- 7\right)\right] - 3 \left(- 4\right)$
$\left[- 4 + 4\right] - 3 \left(- 4\right)$
$0 - 3 \left(- 4\right)$
$0 + 12$
$12$
