👉 "tuppenny" is a term in the context of mathematics and finance that refers to an investment where the investor pays a fee or commission, typically 10%, on their initial investment. This fee is usually paid at the start of the investment period, which can be one year or more. The purpose of this fee is to ensure that investors are compensated for the risk they take by investing in a particular asset and to encourage them to continue with the investment over time.
