Complex numbers include both real and imaginary parts and are represented as 'a + bi,' where 'a' is the real part, 'b' is the imaginary part, and 'i' is the imaginary unit.

Learn how to add, subtract, multiply, and divide complex numbers. For example, (3 + 2i) + (1 - 4i) = 4 - 2i.

Complex conjugates are pairs of complex numbers that, when multiplied, result in a real number. Example: (2 + 3i) * (2 - 3i) = 13.

Complex numbers have applications in various fields, including engineering and physics.

Proficiency in complex numbers is essential for advanced algebra and calculus.
