This is a basic video on the operations and calculations with complex numbers like division and multiplication. By using an example I show how to simplfy expressions involving complex numbers. Such ideas are seen in high-school and first-year university mathematics. Complex numbers are an extension of the well--known real numbers. Complex numbers (and complex--valued functions) find useful applications in signal analysis; fluid mechanics; relativity; and quantum mechanics. A solid understanding of basic calculations with complex numbers empower us to do more significant and interesting things with them.
