Properties of Complex Numbers:
Given that X, Y, and Z are real numbers, then the following are
Definition of i: i =
√(-1) and i2 = -1. "i" is referred to as an
Extract i From a Square Root:
√(-A) = i
√A where -A is a real number < 0.
We could also cite this property as the Definition of i.
Standard Form: Every complex number may be written in
the form A + Bi where A and B are real number coefficients and i is
the square root of -1. This is known as the "Standard Form" of a
Real Number Properties Apply to Complex Numbers: All Basic
Properties of Real Numbers apply to complex numbers. In other words,
we can multiply out terms with the Distributive Property,
Combine Like Terms, etc.
