Financial calculators have been used in business circles for many years, but rarely have been used in schools. Financial mathematics does not rate highly in many school curricula, and is often taught outside mathematics departments in colleges and universities. In this workshop, we will explore some everyday situations involving money, and consider how a modern graphics calculator (with financial capabilities) renders them more accessible. Along the way, we will make some observations about the way school mathematics deals with financial questions and hopefully give you an opportunity to better understand some of your own personal financial circumstances. We will use Casio cfx-9850GB PLUS calculators, especially the TVM mode, but will not assume that you already have experience with these.
