Adding a negative number to a positive number is the same as subtracting the value. Therefore, the answer should be 14.4

$42.3+(-27.9)$ is our starting equation. Since all of the terms inside the parenthesis are negative:

$+(-27.9)$ is the same thing as saying $-27.9$

Then we can re-form the equation as:

$42.3-27.9 = 14.4$
