what I am receiving now

The input numbers are:
(4,4)
(6,7)
(2.5,9.3)
(3,8.4)
(13,26.5)
(2.2,3.4)
Finish the input

&operator +
c.Real is 2.4
c.Imaginary is 9.3
d is 4.5
result is (7,9.3)

The sum is a complex number (7,9.3)

What I need to get:

The input numbers are:
(4,4)
(6,7)
(2.5,9.3)
(3,8.4)
(13,26.5)
(2.2,3.4)
Finish the input
The sum is a complex number (10,11)
The sum is a complex number (7,9.3)
The sum is a complex number (7.5,8.4)
The subtract is a complex number (10.8,23.1)
The product is a complex number (-183.6,188.7)
The subtract is a complex number (0.5,4)
The product is a complex number (58.5,119.25)

Thanks for any help!

If you could say how those values should be obtained, that would be great.
As it is now, you are missing six operations.

Also, if you don't want
&operator +
c.Real is 2.4
c.Imaginary is 9.3
d is 4.5
to appear, then don't print it.
