What degree in college do you get as you are officially a mathematician?

To be considered a mathematician, one typically holds at least a bachelor's degree in mathematics or a related field. Many professional mathematicians pursue advanced degrees, such as a master's or Ph.D. in mathematics, to deepen their expertise and engage in research. However, the title of "mathematician" is not regulated, so individuals with varying educational backgrounds can identify as mathematicians based on their work and contributions to the field.
