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

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

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