I got -10+-14 but I'm not sure if that's correct. Would like to make sure before submitting an answer, considering it's an online assignment and I can only get so many wrong.

Just sum like terms which you did. You can leave out the + sign.

that's what I wasn't sure about. I know sometimes you have to rewrite the problem depending on the signs..but not sure exactly when. So it would be -10-14 ?
