The video tutorial covers solving a problem using conditional logic in programming. It starts with an introduction to the problem and explains how to use if-else statements for arithmetic operations like addition, subtraction, division, and multiplication. The program is demonstrated with examples, and errors are corrected to ensure all operations work correctly. The tutorial concludes by suggesting the use of a switch statement for simplifying the logic, which will be discussed in the next video.
