Need to find the sum of (-7-8i)+(-3-6i)

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

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 ?

OpenStudy (anonymous):

Don't forget the i on the 14. So -10-14i

OpenStudy (anonymous):

oh yep. Thanks :)
