Financial mathematics

Financial mathematics is a subject that combines maths concepts with financial concepts. It deals with the mathematics of money - how money works and how it can be used to make decisions. Financial mathematics looks at things like using maths equations to decide how much to invest in something or how much to save for retirement. It can also help with planning budgets and understanding interest rates. Basically, it's all about using mathematical concepts to make sense of money and make decisions with it.
