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

Answer 1

#-9#

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.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
