Question

Add. Express your answer in standard form. (−3+5i)+(6+2i). Enter your answer in the box.

Answer 1

You add/subtract complex numbers simply by adding/subtracting real parts and imaginary parts.

So, the real part of this sum is the sum of the real parts:

`-3+6=3`

And the imaginary part of this sum is the sum of the imaginary parts:

`5i+2i=7i`

So, you have

`(-3+5i)+(6+2i) = 3+7i`
