This research aims to explore and analyze the impact that understanding mathematics can have on an individual's morality and belief perception. The research addresses elements of mathematical philosophy that may cause the values and morals of individuals who participate in the study of mathematics to be deeply shaped. The analysis revolves around how mathematics integrates with rationality and how this integration can lead to the formation and strengthening of moral values. The study relies on the interpretive approach to understand the personal experiences and meanings that individuals give to their understanding of mathematics and how this is reflected in their values and ethics. The research includes a critical review of relevant literature. The results showed that there is a positive impact of understanding mathematics on morals and beliefs, as deep interaction with mathematics contributes to the formation and development of individuals' values and their understanding of the world.
