The video tutorial explains the implementation of arithmetic operations in a bank account class, focusing on addition (deposit) and subtraction (withdrawal). It introduces a check object and demonstrates how to handle deposits with checks, including error handling for mismatched account numbers. The tutorial covers class definitions, method implementations, and operator overloading. It concludes with testing and debugging the code to ensure correct functionality.
