Strategies
Knowledge of numerical operations and polynomial operations are encouraged to ensure success on this exercise.
 * 1) The product of complex numbers are performed by using distribution and then replacing i^2 with the value of -1.
 * 2) The value of $$(a+bi)(c+di)$$ is $$(ac-bd)+(bc+ad)i$$.

Real-life Applications

 * 1) Complex numbers have applications as models in non-Euclidean geometries.
 * 2) Complex numbers are used to create fractal images.
 * 3) Complex numbers are a natural extension of the real numbers.
