Compound Interest Formula Practice

① This example demonstrates the application and interpretation of the compound interest formula FV = PV × (1 + r)^n through randomly generated practice problems. ② Core math concepts include compound interest, future value, present value, interest rate, number of periods, and exponential growth. ③ Construction highlights: uses GeoGebra commands such as RandomElement to select random periods, FutureValue to compute future value, Textfield and InputBox for user input, and If to check answers, with multiple text objects for problem display and feedback. ④ Suitable for high school or college courses in financial mathematics or algebra, as an interactive exercise for practicing compound interest calculations and understanding the formula.
