To solve this expression, we can follow the order of operations (PEMDAS/BODMAS) which states that we should perform any calculations within parentheses or brackets first, then do any multiplication or division from left to right, and finally perform any addition or subtraction from left to right.
-14.25 + -3.78 - (-5.78) - 3.4
= -14.25 + -3.78 + 5.78 - 3.4
= -14.25 + 5.78 - 3.78 - 3.4
= -8.47 - 3.78 - 3.4
= -12.25 - 3.4
= -15.65
So the final answer is -15.65
