The sum of 3+2i+1-5i is found by adding the real terms together and the complex terms, or the terms that contain i, together.
3+2i+1-5i
=> 3 + 1 + 2i - 5i
=> 4 - 3i
The required result of 3+2i+1-5i is 4 - 3i

We'll recognize the complex numbers from this addition:
z1 = 3+2i and z2 = 1-5i
We'll combine 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, whose real part is Re(z) = 4 and the imaginary part is Im(z) = -3.
