I would say that you would need to demonstrate that you understand that i is a number which when squared equals -1. Also demonstrate how complex numbers can be represented graphically, both as rectangular coordinates an polar coordinates. Another thing would be an understanding of Euler's relationship: e^(i*Θ) = cos(Θ) + i*sin(Θ). Note that Θ must be in radians for this to work.

### Are complex numbers the greatest number system?

The set of complex numbers encompasses real, imaginary, and
combinations of the two, so it is the largest set that you
are likely to encounter. There are other number systems, such as
quaternion imaginaries, which you may never encounter, so I only
mention it here and you can look it up for more info if you're
interested.
