The Interplay of Mathematics and Finance
Mathematics has been applied to problems involving loans and investments from very early times. The Mesopotamians were calculating compound interest around 2000 BC. Later, in India and China, problems of debt were used to motivate negative numbers. The connections have only strengthened with time and the flow of ideas has been especially rich in the last century. We give a brief history of these connections and also explore the role of finance in the teaching of mathematics and as a career for mathematicians.
