The video tutorial explains the concept of imaginary numbers, focusing on the imaginary unit I. It demonstrates how to multiply polynomials using the box method, treating I as a variable. The tutorial further explains the significance of I squared, which equals -1, and how it affects calculations. The instructor emphasizes understanding the process of replacing variables with I and the resulting expressions.
