The notation Ae^(i*theta) is one of the three commonly used for complex numbers.

A = magnitude of vector in complex space
e = euler's constant
i = sqrt(-1)
theta = angle of vector in complex space

-1 is a complex number as well (-1 + 0i). So it also obeys these rules. Basically when you multiply -1 with -1 the product is a number that has been rotated 180 degrees (1). This applies to all negative numbers.
