We teach the first-year students of computer university in Myanmar about the relationships between different sorts of numbers in Discrete Mathematics. In this paper, we discuss ways in which computer technology can be used to learn integer representations of number theory in discrete mathematics. In today’s world, the computing component is essential in every applied math courses. While students come from various programming background using different programming languages, it is more practical to use a single computing language throughout the course. MATLAB is a helpful software for mathematical computation. This is the best idea to learn integer representation problems by using computer programming. It is important to get theory skills and knowledge of viewing practical testing. Traditionally, covering the theory is needed to do practical working.
