The video tutorial explains how to calculate the factorial of a number using recursion. It begins with an introduction to factorials and their mathematical notation. The base case for recursion is identified as the factorial of zero, which is one. The tutorial then demonstrates how to implement the factorial function in code, including test cases for validation. The recursive logic is explained, showing how each factorial can be expressed in terms of the previous one. The function is finalized and tested, and the video concludes with a preview of the next topic: calculating Fibonacci numbers using recursion.
