- 1. Pure mathematics is the study of mathematical concepts independently of any application outside of mathematics itself. It explores abstract ideas and theoretical constructs, seeking to understand the fundamental principles that underlie various mathematical systems. Pure mathematics plays a crucial role in the development of new mathematical theories and techniques, as well as in advancing our understanding of complex mathematical structures. Mathematicians engaged in pure mathematics often strive to prove theorems and conjectures, pushing the boundaries of mathematical knowledge and contributing to the ongoing exploration of the mathematical universe.
