Some people can think in numbers in a way that does not require visual representation or any kind of representation, and as such, it is also possible for such a person to express the pure idea in different ways, including numbers as shapes as the author is doing.
'Cause I am very curious how the author experiences imaginary and complex numbers ... or even negative integers, irrationals, and transcendental numbers.
Negative numbers are just like the positive ones, but kind of... the opposite. Like the indentation formed if you pressed the positive number into clay or sand or something. It's like they want to be filled or take away from something else rather than adding onto other forms.
RE how I think about imaginary or complex numbers, in short, I don't :)
I've never studied much higher math, and don't have any reason to think that I'd be particularly good at it.
