The Math Major

The video tutorial explores the two main subfields of mathematics: applied math and pure math. Applied math focuses on solving real-world problems using mathematical concepts, while pure math deals with solving problems within mathematics itself. The tutorial covers various applied math courses, such as calculus, differential equations, and numerical analysis, highlighting their applications in fields like engineering and physics. It also introduces pure math, emphasizing the importance of proofs and abstract algebra. The video aims to provide insights into the different paths and careers available in mathematics.
