Here are two different complex numbers:

2 +j4 and 1 +j3

Here is how to show that the two values are to be added:

(2 +j4) **+** (1 +j3)

To add these numbers, first **add the real parts** (**2** +j4) + (**1** +j3):

2 + 1 = 3

Then **add the imaginary parts** (2 +**j4**) + (1 +**j3**):

j4 + j3 = j7

Putting together the real and imaginary parts of the sums:

3 + j7

So the overall result is:

(2 + j4) + (1 +j3) = 3 +j7
