The description that is intuitive for me is that multiplying a number
on the x-axis by integer powers of -1 cause rotation by 180 degrees.
Logically, to rotate by 90 degrees one should multiply by a number
that you multiply by it again will give 180 degrees of rotation. This
number is the square root of -1.
