1. The question asks about Einstein's role in the math field. 2. Albert Einstein was primarily a physicist, but his work deeply involved advanced mathematics. 3. He used mathematical concepts such as differential geometry and tensor calculus to develop the theory of general relativity. 4. His role in math was applying and advancing mathematical tools to solve physical problems, not creating new branches of pure mathematics. 5. Therefore, Einstein's contribution to math is significant in applied mathematics, especially in mathematical physics.
