We have to add 3 + 2i + 1 -5i.

When adding complex and real numbers complex terms can be added with each other only. The same goes for the real terms.

So 3 + 2i + 1 -5i

=> 3 + 1 + 2i -5i

=> 4 - 3i

The required result is 4 - 3i.

To add the complex numbers.

3+2i+1-5i.

Add the real numbers  and add the complex nnumbers.

3+2i+1-5i = (3+1)+(2i-5i).

3+2i+1-5i = 4+(2-5)i.

3+2i+1-5i  = 4 -3i.

The complex numbers from this addition are:

z1 = 3+2i and z2 = 1-5i

We'll add the real parts and the imaginary parts:

(3+1) + (-5i+2i)

4 - 3i

The complex number resulted from the addition of the given complex numbers z1 and z2 is:

z = z1 + z2

z = 4 - 3i, where the real part is Re(z) = 4 and the imaginary part is Im(z) = -3.
