Question

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

Answer 1

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.

Answer 2

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

Answer 3

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 ?

Answer 4

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

Answer 5

oh yep. Thanks :)

Answer 6

No problem.
