Complex Numbers | How to Add Subtract Multiply Divide | ArmanisMath

ArmanisMath presents an engaging lecture on Complex Numbers math Operations. How to Add, Subtract, Multiply, and Divide Complex Numbers. I also explain how to use Complex Numbers in Solving the Quadratic Formula. We learn about the three cases of the Discriminant in the quadratic formula, and how each helps predict different solutions. Examples are intended to build students' confidence and increase engagement through numerous Checking for Understanding (CFUs).
