Complex Number Operations and Properties

The video tutorial explains how to multiply three complex numbers by breaking the process into steps. It starts with multiplying the first two complex numbers using distribution, treating them like binomials. After finding the product, the result is multiplied by the third complex number. The tutorial emphasizes the importance of substituting i squared with negative one and combining like terms to simplify the expression. The final product of the three complex numbers is calculated, and the tutorial concludes with a summary of the process.
