What do you need to know to multiply complex numbers

This video tutorial covers the essentials of multiplying complex numbers. It begins with an introduction to the distributive property, followed by methods like FOIL and the box method for handling binomials and trinomials. The tutorial then explains the imaginary unit I, its powers, and how to simplify expressions involving I. Finally, it discusses combining like terms to simplify complex expressions into the standard form A + BI.
