#### Explanation:

For this problem, we will need to have knowledge of the order of operations.

Parentheses
Exponents
Multiplication
Division
Subtraction.

In order from top to bottom.

..................................................................................................................

Using the order of operations we know that first we need to solve what is inside the parentheses.

$22 - 2 \left(13 - 7 + 3\right)$

$22 - 2 \left(6 + 3\right)$

$22 - 2 \left(9\right)$

..................................................................................................................

Now, we are going to do the multiplication, because that is before subtraction on our order of operations.

$22 - 2 \left(9\right)$

$22 - 18$

..................................................................................................................

Now, we just have to do basic subtraction.

$22 - 18 = 4$

This brings us to our final answer of 4.
