How is it possible to ignore the addition sign and imaginary number without contradicting fundamental Mathematics?

I find it difficult to understand.

Hi,
We don't ignore anything. Don't contradict anything either.
is not correct. Where did you get this ?

It is just a different way to represent the numbers.
By giving the real and imaginary part of a complex number you can uniquely identify this number.

An analogy in the positive integers: You can write every number by its prime factorization.
You can write 2*3*5 or "2,3,5" instead of 30. Same thing, just written in a different way, and there is a 1:1 relation between numbers and their prime factorization.

True that. I have edited it. But my question is correct and after thinking about it, I have found the answer myself. I just find it hard to put into words the exact thing in my mind. That's why the question is incomprehensible. But I think fresh_42 has understood my question.

Thank you for the answer BvU :)
