Question

How do you add `(-2 + 5i) + (-4 - 2i)`?

Answer 1

`-6+3i`

Explanation:

Complex numbers in rectangular form may be added directly, ie you simply add the real and imaginary components individually.

That is, `(a+ib)+(x+iy)=(a+b)+i(x+y)`

So in this particular case :

`(-2+5i)+(-4-2i)=(-2-4)+i(5-2)`

`=-6+3i`.
