Classifying Complex Numbers: Real or Imaginary

The video tutorial explains the concepts of real and imaginary numbers, introducing the imaginary unit 'i' and its properties. It then defines complex numbers as numbers in the form a + bi, where a and b are real numbers. The tutorial further explains how to classify complex numbers as either real or imaginary based on the imaginary term. Examples are provided to illustrate the classification process, emphasizing that a complex number is real if its imaginary term is 0i, and imaginary if the term is not 0i.

What are real numbers and how do they differ from imaginary numbers?
