#### Explanation:

First multiply $- \times \left(- 5\right)$ working from left to right.
Remember PEMDAS (a good way to remember this is: "If you get hurt in PE call an MD ASap")

So the first thing to do is remove parentheses by multiplying .

$8 - \left(- 5\right) - 4 \left(- 7\right)$

$\Rightarrow 8 + 5 - 4 \times \left(- 7\right)$

Continue multiplying across the parentheses $4 \times \left(- 7\right)$

$8 + 5 - 4 \times \left(- 7\right)$

$\Rightarrow 8 + 5 + 28$

Now go to Addition and Subtraction (ASap) working from left to right.

$8 + 5 + 28$

$\Rightarrow 13 + 28$

$\Rightarrow 41$
