Question

How do you simplify `(- 3- 5i ) - ( - 3+ 4i )`?

Answer 1

`-9`

Explanation:

Start with distributing the negative infront of the second set of parenthesis. And after that, you can pretty much drop the parenthesis, which is visually better (at least for me!):

`-3-5i+3-4i`

Combine like terms:

`-9i`

Considering it's using imaginary numbers, it's hard to do anything, so the most you can do is simplify.
