$95$

#### Explanation:

Adding and subtracting with positive and negative values often leads to confusion.

Note that a sign in front of a number applies ONLY to that number.

So $18 - 7 + 5$ does NOT mean the same as $18 - \left(7 + 5\right)$
The answers for these are $16 \mathmr{and} 6$

The easiest way to avoid confusion is to re-arrange the numbers we are allowed to do (which according to the commutative law).

Place the additions at the front of the expression and the subtractions at the end.

$125 - 43 + 13$ is better understood as:

$125 + 13 - 43$

=$95$
